What's New
This document shows you what’s new in the latest release and flags it with one of the following badges. For a detailed list of changes, see the history page.
0.112.4 The minimum required Hugo version.
Breaking A change that requires action by you after upgrading to assure the site is still functional.
Change A change in default behavior that may requires action by you if you want to revert it.
New Marks new behavior you might find interesting or comes configurable.
5.24.0.beta
0.112.4 This release requires a newer Hugo version.
Change The light themes have a bit more contrast for content text and headings. Also the syntaxhighlighting was changed to the more colorful MonokaiLight. This brings the syntaxhighlightning in sync with the corresponding dark theme variants, which are using Monokai. If you dislike this, you can create your own color variant file as described here.
New You now can configure additional options for every theme variant in your hugo.toml. This allows for optional advanced functionality. You don’t need to change anything as the old configuration options will still work (but may generate warnings now).
The advanced functionality allows you to set an explicit name for a theme variant, set different colors (if you are using monochrome SVGs) or even different icons (handy if you want to adjust colors for PNGs, GIFs or JPGs) and now allows for multiple auto mode variants that adjust to the light/dark preference of your OS settings.
New New partial for defining the heading. See documentation for further reading.
5.23.0 (2023-11-03)
Change With 0.120.0 the author settings move into the [params] array in your hugo.toml. Because this collides with the previous way, the theme expected author information, it now adheres to Hugo standards and prints out a warning during built if something is wrong.
Change your previous setting from
[params]author="Hugo"
to
[params]author.name="Hugo"
Change Taxonomy term pages now add the breadcrumb for each listed page. If this gets too crowded for you, you can turn the breadcrumbs off in your hugo.toml by adding disableTermBreadcrumbs=true.
New Taxonomy and term pages are now allowed to contain content. This is added inbetween the title and the page list.
New It is now possible to print custom taxonomies anywhere in your page. See the docs.
New It is now possible to adjust the menu width for your whole site. See the docs.
New This release adds social media meta tags for the Open Graph protocol and Twitter Cards to your site. See the docs.
New This release comes with additional sort options for the menu and the children shortcode. Both will now accept the following values: weight, title, linktitle, modifieddate, expirydate, publishdate, date, length or default (adhering to Hugo’s default sort order).
New The theme now provides a mechanism to load further JavaScript dependencies defined by you only if it is needed. This comes in handy if you want to add own shortcodes that depend on additional JavaScript code to be loaded. See the docs.
New The theme has updated its Mermaid dependency to 10.6.0. This adds support for the xychart type.
New This release adds portable Markdown links.
Previously it was not possible to use pure Markdown links in a configuration independend way to link to pages inside of your project. It always required you to know how your uglyURLs setting is, wheather you link to a page or page bundle and in case of relative links if your current page is a page or page bundle. (eg. [generator](generator/index.html) vs. [generator](generator.html)). This is a hassle as you have to change these links manually once you change your uglyURLs setting or change the type of a page.
You could work around this by using the relref shortcode (eg [generator]({{% relref "../generator" %}})) which works but results in non-portable Markdown.
Now it’s possible to use the same path of a call to relref in a plain Markdown link (eg [generator](../generator)). This is independend of any configuration settings or the page types involved in linking. Note, that this requires your links to be given without any extension, so [generator](generator/index.html) will work as before.
The following types of linking are supported:
link
description
[generator](en/basics/generator)
absolute from your project root (multilang)
[generator](/en/basics/generator)
absolute from your project root (multilang)
[generator](basics/generator)
absolute from your current language root
[generator](/basics/generator)
absolute from your current language root
[generator](./../generator)
relative from the current page
[generator](../generator)
relative from the current page
5.22.0 (2023-10-02)
Change This release fixes an issue where in unfortunate conditions DOM ids generated by Hugo may collide with DOM ids set by the theme. To avoid this, all theme DOM ids are now prefixed with R-.
If you haven’t modified anything, everything is fine. Otherwise you have to check your custom CSS rules and JavaScript code.
Change You can now have structural sections in the hierarchical menu without generating a page for it.
This can come in handy, if content for such a section page doesn’t make much sense to you. See the documentation for how to do this.
This feature may require you to make changes to your existing installation if you are already using shortcuts to pages inside of your project with a headless branch parent.
In this case it is advised to remove the title from the headless branch parent’s frontmatter, as it will otherwise appear in your breadcrumbs.
New It is now possible to overwrite the setting for collapsibleMenu of your hugo.toml inside of a page’s frontmatter.
New If a Mermaid graph is zoomable a button to reset the view is now added to the upper right corner. The button is only shown once the mouse is moved over the graph.
New It is now possible to remove the root breadcrumb by setting disableRootBreadcrumb=true in your hugo.toml.
New The output of the dedicated search page now displays the result’s breadcrumb.
New Table rows now change their background color on every even row.
New Translation into Swahili. This language is not supported for search.
5.21.0 (2023-09-18)
Change We made changes to the menu footer to improve alignment with the menu items in most cases. Care was taken not to break your existing overwritten footer. Anyways, if you have your menu-footer.htmlpartial overridden, you may want to review the styling (eg. margins/paddings) of your partial.
New This release comes with an awesome new feature, that allows you to customize your topbar buttons, change behavior, reorder them or define entirely new ones, unique to your installation. See the documentation for further details.
New The theme has updated its Swagger dependency to 5.7.2 for the openapi shortcode. This brings support for OpenAPI Specification 3.1.
5.20.0 (2023-08-26)
Change The theme has updated its Swagger dependency to 5.4.1 for the openapi shortcode.
With this comes a change in the light theme variants of Relearn Bright, Relearn Light and Zen Light by switching the syntaxhighlightning inside of openapi to a light scheme. This brings it more in sync with the code style used by the theme variants itself.
Additionally, the syntaxhighlightning inside of openapi for printing was switched to a light scheme for all theme variants.
If you dislike this change, you can revert this in your theme variants CSS by adding
Change For consistency reasons, we renamed the CSS variable --MENU-SECTION-HR-color to --MENU-SECTION-SEPARATOR-color. You don’t need to change anything in your custom color stylesheet as the old name will be used as a fallback.
New The theme variants Zen Light and Zen Dark now add more contrast between menu, topbar and content by adding thin borders.
Those borders are now configurable by using the CSS variables --MAIN-TOPBAR-BORDER-color, --MENU-BORDER-color, --MENU-TOPBAR-BORDER-color, --MENU-TOPBAR-SEPARATOR-color, --MENU-HEADER-SEPARATOR-color and --MENU-SECTION-ACTIVE-CATEGORY-BORDER-color.
For existing variants nothing has changed visually.
New The default values for the image effects are now configurable for your whole site via hugo.toml or for each page thru frontmatter.
New This release fixes a long outstanding bug where Mermaid graphs could not be displayed if they were initially hidden - like in collapsed expand or inactive tabs.
New Restored compatibility with Hugo versions lower than 0.111.0 for the highlight shortcode. This does not change the minimum required Hugo version.
5.19.0 (2023-08-12)
New The highlight shortcode now accepts the new parameter title. This displays the code like a single tab. This is also available using codefences and makes it much easier to write nicer code samples.
New The theme has added two new color variants zen-light and zen-dark. Check it out!
New The theme now dispatches the custom eventthemeVariantLoaded on the document when the variant is fully loaded either initially or by switching the variant manually with the variant selector.
New The theme has updated its Mermaid dependency to 10.3.1. This adds support for the sankey diagram type and now comes with full support for YAML inside Mermaid graphs (previously, the theme ignored explicit Mermaid theme settings in YAML).
New Translation into Hungarian.
5.18.0 (2023-07-27)
Change The theme adds additional warnings for deprecated or now unsupported features.
Change There are visual improvements in displaying text links in your content aswell as to some other clickable areas in the theme. If you’ve overwritten some theme styles in your own CSS, keep this in mind.
New Restored compatibility with Hugo 0.95.0 or higher. This does not change the minimum required Hugo version.
New The siteparam shortcode is now capable in displaying nested params aswell as supporting text formatting.
5.17.0 (2023-06-22)
Change The default behavior for the copy-to-clipboard feature for code blocks has changed.
The copy-to-clipboard button for code blocks will now only be displayed if the reader hovers the code block.
If you dislike this new behavior you can turn it off and revert to the old behavior by adding [params] disableHoverBlockCopyToClipBoard=true to your hugo.toml.
New Restored compatibility with Hugo 0.114.0 or higher. This does not change the minimum required Hugo version.
New The new highlight shortcode replaces Hugo’s default implementation and is fully compatible. So you don’t need to change anything.
In addition it offers some extensions. Currently only the wrap extension option is provided to control whether a code block should be wrapped or scrolled if to long to fit.
5.16.0 (2023-06-10)
Change The theme now provides warnings for deprecated or now unsupported features. The warnings include hints how to fix them and an additional link to the documenation.
DEPRECATION warnings mark features that still work but may be removed in the future.
UNSUPPORTED warnings mark features that will not work anymore.
Change The 404 error page was revamped. Hopefully you will not see this very often.
New The tabs shortcode and the tab shortcode received some love and now align with their style, color, title and icon parameter to the other shortcodes.
The visuals are now slightly different compared to previous versions. Most noteable, if you now display a single code block in a tab, its default styling will adapt to that of a code block but with a tab handle at the top.
Additionally the name parameter was renamed to title but you don’t need to change anything yet as the old name will be used as a fallback. Nevertheless you will get deprecation warnings while executing Hugo.
New The theme now optionally supports separate favicons for light & dark mode.
5.15.0 (2023-05-29)
Change Restored compatibility with Hugo 0.112.0 or higher. This does not change the minimum required Hugo version.
The attachments shortcode has compatiblity issues with newer Hugo versions. You must switch to leaf bundles or are locked to Hugo < 0.112.0 for now.
It is planned to refactor the attchments shortcode in the future. This will make it possible to use the shortcode in branch bundles again but not in simple pages anymore. This will most likely come with a breaking change.
Change The tabs shortcode has changed behavior if you haven’t set the groupid parameter.
Formerly all tab views without a groupid were treated as so they belong to the same group. Now, each tab view is treated as it was given a unique id.
New The already known tabshas a new friend the tab shortcode to make it easier to create a tab view in case you only need one single tab. Really handy if you want to flag your code examples with a language identifier.
Additionally for such a use case, the whitespace between a tab outline and the code is removed if only a single code block is contained.
New Besides the tagtaxonomy the theme now also provides the category taxonomy out of the box and shows them in the content footer of each page.
5.14.0 (2023-05-20)
New The taxonomy pages received some love in this release, making them better leverage available screen space and adding translation support for the taxonomy names.
Hugo’s default taxonmies tags and categories are already contained in the theme’s i18n files. If you have self-defined taxonomies, you can add translations by adding them to your own i18n files. If you don’t provide translations, the singualar and plural forms are taken as configured in your hugo.toml.
New To give you more flexibility in customizing your article layout a new partial content-header.html is introduced.
This came out of the requirement to customize the position of article tags, which by default are displayed above the title. A second requirement was to also show additional taxonomies not supported by the theme natively. While Hugo supports tags and categories by default, the theme only displays tags.
So how to adjust the position of tags starting from the theme’s default where tags are only shown above the title?
Hide tags above title: Overwrite content-header.html with an empty file.
Show tags between title and content: Overwrite heading-post.html and add {{- partial "tags.html" . }} to it.
Show tags below content: Overwrite content-footer.html and add {{- partial "tags.html" . }} to it.
New The new parameter breadcrumbSeparator is now available in your hugo.toml to change the - well - separator of the breadcrumb items. An appropriate default is in place if you do not configure anything.
5.13.0 (2023-05-17)
Change The swagger shortcode was deprecated in favor for the openapi shortcode. You don’t need to change anything yet as the old name will be used as a fallback. It is planned to remove the swagger shortcode in the next major release.
Additionally, the implemantion of this shortcode was switched from RapiDoc to SwaggerUI.
5.12.0 (2023-05-04)
Change In the effort to comply with WCAG standards, the implementation of the collapsible menu was changed (again). While Internet Explorer 11 has issues in displaying it, the functionality still works.
The theme provides Front Matter snippets for its shortcodes. Currently only English and German is supported. Put a reference into your frontmatter.json like this
New Support for languages that are written right to left (like Arabic) is now complete and extended to the menu, the top navigation bar and print. You can experience this in the pirate translation. This feature is not available in Internet Explorer 11.
New The scrollbars are now colored according to their variant color scheme to better fit into the visuals.
5.11.0 (2023-02-07)
Change The theme removed the popular jQuery library from its distribution.
In case you made changes to the theme that are dependend on this library you can place a copy of jQuery into your static/js directory and load it from your own layouts/partials/custom-header.html like this:
This is also the new default setting if you haven’t configured themeVariant in your hugo.toml.
Additionally you can configure the variants to be taken for light/dark mode with the new themeVariantAuto parameter.
This is not supported for Internet Explorer 11, which still displays in the relearn-light variant.
Change The JavaScript code for handling image lightboxes (provided by Featherlight) was replaced by a CSS-only solution.
This also changed the lightbox effects parameter from featherlight=false to lightbox=false. Nevertheless you don’t need to change anything as the old name will be used as a fallback.
Change In the effort to comply with WCAG standards, the implementation of the expand shortcode was changed. While Internet Explorer 11 has issues in displaying it, the functionality still works.
New Translation into Czech. This language is not supported for search.
NewGitHub releases are also now tagged for the main version (eg. 1.2.x), major version (eg. 1.x) and the latest (just x) release making it easier for you to pin the theme to a certain version.
5.10.0 (2023-01-25)
New The attachments, badge, button and notice shortcodes have a new parameter color to set arbitrary CSS color values.
Additionally the --ACCENT-color brand color introduced in version 5.8.0 is now supported with these shortcodes.
5.9.0 (2022-12-23)
Breaking With this version it is now possible to not only have sections on the first menu level but also pages.
It was later discovered, that this causes pages only meant to be displayed in the More section of the menu and stored directly inside your content directory to now show up in the menu aswell.
To get rid of this undesired behavior you have two choices:
Make the page file a headless branch bundle (contained in its own subdirectory and called _index.md) and add the following frontmatter configuration to the file (see exampleSite’s content/showcase/_index.en.md). This causes its content to not be ontained in the sitemap.
Store the page file for below a parent headless branch bundle and add the following frontmatter to he parent (see exampleSite’s content/more/_index.en.md).
# title = "More" ### ATTENTION: Don't give this page a title as this will cause it to be in the breadcrumbs - a thing you most likely don't want[_build]render="never"list="never"publishResources=false
In this case, the file itself can be a branch bundle, leaf bundle or simple page (see exampleSite’s content/more/credits.en.md). This causes its content to be contained in the sitemap.
title="Credits"
Change The required folder name for the attachments shortcode was changed for leaf bundles.
Previously, the attachments for leaf bundles in non-multilang setups were required to be in a files subdirectory. For page bundles and leaf bundles in multilang setups they were always required to be in a _index.<LANGCODE>.files or index.<LANGCODE>.files subdirectory accordingly.
This added unnessessary complexity. So attachments for leaf bundles in non-multilang setups can now also reside in a index.files directory. Although the old files directory is now deprecated, if both directories are present, only the old files directory will be used for compatiblity.
Change Absolute links prefixed with http:// or https:// are now opened in a separate browser tab.
You can revert back to the old behavior by defining externalLinkTarget="_self" in the params section of your hugo.toml.
New The new badge shortcode is now available to add highly configurable markers to your content as you can see it on this page.
New The new icon shortcode simplyfies the usage of icons. This can even be combined with also new badge shortcode.
New The theme now supports some of GFM (GitHub Flavored Markdown) syntax and Hugo Markdown extensions, namely task lists, defintion lists and footnotes.
New A new color --ACCENT-color was introduced which is used for highlightning search results on the page. In case you simply don’t care, you don’t need to change anything in your variant stylesheet as the old yellow color is still used as default.
5.7.0 (2022-11-29)
Change The Korean language translation for this theme is now available with the language code ko. Formerly the country code kr was used instead.
New The button shortcode can now also be used as a real button inside of HTML forms - although this is a pretty rare use case. The documentation was updated accordingly.
New The search now supports the Korean language.
5.6.0 (2022-11-18)
New This release introduces an additional dedicated search page. On this page, displayed search results have more space making it easier scanning thru large number of results.
To activate this feature, you need to configure it in your hugo.toml as a new outputformat SEARCHPAGE for the home page. If you don’t configure it, no dedicated search page will be accessible and the theme works as before.
You can access the search page by either clicking on the magnifier glass or pressing enter inside of the search box.
New Keyboard handling for the TOC and search was improved.
Pressing CTRL+ALT+t now will not only toggle the TOC overlay but also places the focus to the first heading on opening. Subsequently this makes it possible to easily select headings by using the TAB key.
The search received its own brand new keyboard shortcut CTRL+ALT+f. This will focus the cursor inside of the the search box so you can immediately start your search by typing.
New You are now able to turn off the generation of generator meta tags in your HTML head to hide the used versions of Hugo and this theme.
To configure this in your hugo.toml make sure to set Hugo’s disableHugoGeneratorInject=trueand also [params] disableGeneratorVersion=true, otherwise Hugo will generate a meta tag into your home page automagically.
New Creation of your project gets a little bit faster with this release.
This addresses increased build time with the 5.x releases. The theme now heavily caches partial results leading to improved performance. To further increase performance, unnecessary parts of the page are now skipped for creation of the print output (eg. menus, navigation bar, etc.).
5.5.0 (2022-11-06)
Change The way images are processed has changed. Now images are lazy loaded by default which speeds up page load on slow networks and/or big pages and also the print preview.
For that the JavaScript code to handle the lightbox and image effects on the client side was removed in favour for static generation of those effects on the server.
If you have used HTML directly in your Markdown files, this now has the downside that it doesn’t respect the effect query parameter anymore. In this case you have to migrate all your HTML img URLs manually to the respective HTML attributes.
ChangeWith the proper settings in your hugo.toml your page is now servable from the local file system using file:// URLs.
Please note that the searchbox will only work for this if you reconfigure your outputformat for the homepage in your hugo.toml from JSON to SEARCH. The now deprecated JSON outputformat still works as before, so there is no need to reconfigure your installation if it is only served from http:// or https://.
Change The button shortcode has a new parameter target to set the destination frame/window for the URL to open. If not given, it defaults to a new window/tab for external URLs or is not set at all for internal URLs. Previously even internal URLs where opened in a new window/tab.
New Support for languages that are written right to left (like Arabic). This is only implemented for the content area but not the navigation sidebar. This feature is not available in Internet Explorer 11.
New Translation into Finnish (Suomi).
5.3.0 (2022-10-07)
Change In the effort to comply with WCAG standards, the implementation of the collapsible menu was changed. The functionality of the new implementation does not work with old browsers (Internet Explorer 11).
NewImage formatting has two new classes to align images to the left or right. Additionally, the already existing inline option is now documented.
New Printing for the swagger shortcode was optimized to expand sections that are usually closed in interactive mode. This requires print support to be configured.
5.2.0 (2022-08-03)
Change If you’ve set collapsibleMenu = true in your hugo.toml, the menu will be expanded if a search term is found in a collapsed submenu. The menu will return to its initial collapse state once the search term does not match any submenus.
5.1.0 (2022-07-15)
0.95.0 This release requires a newer Hugo version.
Change Because the print preview URLs were non deterministic for normal pages in comparison to page bundles, this is now changed. Each print preview is now accessible by adding a index.print.html to the default URL.
You can revert this behavior by overwriting the PRINT output format setting in your hugo.tomlto:
Breaking The theme changed how JavaScript and CSS dependencies are loaded to provide a better performance. In case you’ve added own JavaScript code that depends on the themes jQuery implementation, you have to put it into a separate *.js file (if not already) and add the defer keyword to the script element. Eg.
<scriptdefersrc="myscript.js"></script>
Change The way archetypes are used to generate output has changed. The new systems allows you, to redefine existing archetypes or even generate your own ones.
Your existing markdown files will still work like before and therefore you don’t need to change anything after the upgrade. Nevertheless, it is recommended to adapt your existing markdown files to the new way as follows:
for your home page, add the frontmatter parameter archetype = "home" and remove the leading heading
for all files containing the deprecated frontmatter parameter chapter = true, replace it with archetype = "chapter" and remove the leading headings
Change The frontmatter options pre / post were renamed to menuPre / menuPost. The old options will still be used if the new options aren’t set. Therefore you don’t need to change anything after the upgrade.
New Adding new partials heading-pre.html / heading-post.html and according frontmatter options headingPre / headingPost to modify the way your page`s main heading gets styled.
New The new shortcode math is available to add beautiful math and chemical formulae. See the documentation for available features. This feature will not work with Internet Explorer 11.
4.2.0 (2022-06-23)
Breaking The second parameter for the include shortcode was switched in meaning and was renamed from showfirstheading to hidefirstheading. If you haven’t used this parameter in your shortcode, the default behavior hasn’t changed and you don’t need to change anything.
If you’ve used the second boolean parameter, you have to rename it and invert its value to achieve the same behavior.
Change Previously, if the tabs shortcode could not find a tab item because, the tabs ended up empty. Now the first tab is selected instead.
Change The landingPageURL was removed from hugo.toml. You can safely remove this as well from your configuration as it is not used anymore. The theme will detect the landing page URL automatically and will point to the project’s homepage. If you want to support a different link, overwrite the logo.html partial.
New All shortcodes can now be also called from your partials. Examples for this are added to the documentation of each shortcode.
Breaking The custom_css config parameter was removed from the configuration. If used in an existing installation, it can be achieved by overriding the custom-header.html template in a much more generic manner.
Breaking Because anchor hover color was not configurable without introducing more complexity to the variant stylesheets, we decided to remove --MAIN-ANCHOR-color instead. You don’t need to change anything in your custom color stylesheet as the anchors now get their colors from --MAIN-LINK-color and --MAIN-ANCHOR-HOVER-color respectively.
New All shortcodes now support named parameter. The positional parameter are still supported but will not be enhanced with new features, so you don’t need to change anything in your installation.
New The button shortcode received some love and now has a parameter for the color style similar to other shortcodes.
New New colors --PRIMARY-color and --SECONDARY-color were added to provide easier modification of your custom style. Shortcodes with a color style can now have primary or secondary as additional values.
These two colors are the default for other, more specific color variables. You don’t need to change anything in your existing custom color stylesheets as those variables get reasonable default values.
New Translation into Polish. This language is not supported for search.
New The documentation for all shortcodes were revised.
3.4.0 (2022-04-03)
Breaking If you had previously overwritten the custom-footer.html partial to add visual elements below the content of your page, you have to move this content to the new partial content-footer.html. custom-footer.html was never meant to contain HTML other than additional styles and JavaScript.
New If you prefer expandable/collapsible menu items, you can now set collapsibleMenu=true in your hugo.toml. This will add arrows to all menu items that contain sub menus. The menu will expand/collapse without navigation if you click on an arrow.
New You can activate print support in your hugo.toml to add the capability to print whole chapters or even the complete site.
New Translation into Traditional Chinese.
3.3.0 (2022-03-28)
New Introduction of new CSS variables to set the font. The theme distinguishes between --MAIN-font for all content text and --CODE-font for inline or block code. There are additional overrides for all headings. See the theme variant generator of the exampleSite for all available variables.
New The new shortcode swagger is available to include a UI for REST OpenAPI specifications. See the documentation for available features. This feature will not work with Internet Explorer 11.
3.2.0 (2022-03-19)
0.93.0 This release requires a newer Hugo version.
Change In this release the Mermaid JavaScript library will only be loaded on demand if the page contains a Mermaid shortcode or is using Mermaid codefences. This changes the behavior of disableMermaid config option as follows: If a Mermaid shortcode or codefence is found, the option will be ignored and Mermaid will be loaded regardlessly.
The option is still useful in case you are using scripting to set up your graph. In this case no shortcode or codefence is involved and the library is not loaded by default. In this case you can set disableMermaid=false in your frontmatter to force the library to be loaded. See the theme variant generator of the exampleSite for an example.
New Additional color variant variable --MERMAID-theme to set the variant’s Mermaid theme. This causes the Mermaid theme to switch with the color variant if it defers from the setting of the formerly selected color variant.
Breaking We made changes to the menu footer. If you have your menu-footer.htmlpartial overridden, you may have to review the styling (eg. margins/paddings) in your partial. For a reference take a look into the menu-footer.html partial that is coming with the exampleSite.
This change was made to allow your own menu footer to be placed right after the so called prefooter that comes with the theme (containing the language switch and Clear history functionality).
Breaking We have changed the default colors from the original Learn theme (the purple menu header) to the Relearn defaults (the light green menu header) as used in the official documentation.
This change will only affect your installation if you’ve not set the themeVariant parameter in your hugo.toml. If you still want to use the Learn color variant, you have to explicitly set themeVariant="learn" in your hugo.toml.
Note, that this will also affect your site if viewed with Internet Explorer 11 but in this case it can not be reconfigured as Internet Explorer does not support CSS variables.
Change Due to a bug, that we couldn’t fix in a general manner for color variants, we decided to remove --MENU-SEARCH-BOX-ICONS-color and introduced --MENU-SEARCH-color instead. You don’t need to change anything in your custom color stylesheet as the old name will be used as a fallback.
Change For consistency reasons, we renamed --MENU-SEARCH-BOX-color to --MENU-SEARCH-BORDER-color. You don’t need to change anything in your custom color stylesheet as the old name will be used as a fallback.
New With this release you are now capable to define your own dark mode variants.
To make this possible, we have introduced a lot more color variables you can use in your color variants. Your old variants will still work and don’t need to be changed as appropriate fallback values are used by the theme. Nevertheless, the new colors allow for much more customization.
To see what’s now possible, see the new variants relearn-dark and neon that are coming with this release.
New To make the creation of new variants easier for you, we’ve added a new interactive theme variant generator. This feature will not work with Internet Explorer 11.
New You can now configure multiple color variants in your hugo.toml. In this case, the first variant is the default chosen on first view and a variant selector will be shown in the menu footer. See the documentation for configuration.
Note, that the new variant selector will not work with Internet Explorer 11 as it does not support CSS variables. Therefore, the variant selector will not be displayed with Internet Explorer 11.
2.9.0 (2021-11-19)
Breaking This release removes the themes implementation of ref/relref in favor for Hugos standard implementation. This is because of inconsistencies with the themes implementation. In advantage, your project becomes standard compliant and exchanging this theme in your project to some other theme will be effortless.
In a standard compliant form you must not link to the *.md file but to its logical name. You’ll see, referencing other pages becomes much easier. All three types result in the same reference:
Type
Non-Standard
Standard
Branch bundle
basics/configuration/_index.md
basics/configuration
Leaf bundle
basics/configuration/index.md
basics/configuration
Page

basics/configuration
If you’ve linked from a page of one language to a page of another language, conversion is a bit more difficult but Hugo got you covered as well.
Also, the old themes implementation allowed refs to non-existing content. This will cause Hugos implementation to show the error below and abort the generation. If your project relies on this old behavior, you can reconfigure the error handling of Hugos implementation.
In the best case your usage of the old implementation is already standard compliant and you don’t need to change anything. You’ll notice this very easily once you’ve started hugo server after an upgrade and no errors are written to the console.
You may see errors on the console after the update in the form:
ERROR 2021/11/19 22:29:10 [en] REF_NOT_FOUND: Ref "basics/configuration/_index.md": "hugo-theme-relearn\exampleSite\content\_index.en.md:19:22": page not found
In this case, you must apply one of two options:
Start up a text editor with regular expression support for search and replace. Search for (ref\s+"[^"]*?)(?:/_index|/index)?(?:\.md)?(#[^"]*?)?" and replace it by $1$2" in all *.md files. This is the recommended choice.
Copy the old implementation files theme/hugo-theme-relearn/layouts/shortcode/ref.html and theme/hugo-theme-relearn/layouts/shortcode/relref.html to your own projects layouts/shortcode/ref.html and layouts/shortcode/relref.html respectively. This is not recommended as your project will still rely on non-standard behavior afterwards.
2.8.0 (2021-11-03)
Change Although never officially documented, this release removes the font Novacento/Novecento. If you use it in an overwritten CSS please replace it with Work Sans. This change was necessary as Novacento did not provide all Latin special characters and lead to mixed styled character text eg. for Czech.
New The theme now supports favicons served from static/images/ named as favicon or logo in SVG, PNG or ICO format out of the box. An overridden partial layouts/partials/favicon.html may not be necessary anymore in most cases.
New You can hide the table of contents menu for the whole site by setting the disableToc option in your hugo.toml. For an example see the example configuration.
2.7.0 (2021-10-24)
New Optional second parameter for notice shortcode to set title in box header.
2.6.0 (2021-10-21)
New Your site can now be served from a subfolder if you set baseURL and canonifyURLs=true in your hugo.toml. See the documentation for a detailed example.
2.5.0 (2021-10-08)
Change New colors --CODE-BLOCK-color and --CODE-BLOCK-BG-color were added to provide a fallback for Hugos syntax highlighting in case no language was given or the language is unsupported. Ideally the colors are set to the same values as the ones from your chosen chroma style.
2.4.0 (2021-10-07)
Change Creation of customized stylesheets was simplified down to only contain the CSS variables. Everything else can and should be deleted from your custom stylesheet to assure everything works fine. For the predefined stylesheet variants, this change is already included.
New Hidden pages are displayed by default in their according tags page. You can now turn off this behavior by setting disableTagHiddenPages=true in your hugo.toml.
New You can define the expansion state of your menus for the whole site by setting the alwaysopen option in your hugo.toml. Please see further documentation for possible values and default behavior.
New New frontmatter ordersectionsby option to change immediate children sorting in menu and children shortcode. Possible values are title or weight.
New Alternate content of a page is now advertised in the HTML meta tags. See Hugo documentation.
2.3.0 (2021-09-13)
0.81.0 This release requires a newer Hugo version.
New Showcase multilanguage features by providing a documentation translation “fer us pirrrates”. There will be no other translations besides the original English one and the Pirates one due to maintenance constraints.
2.2.0 (2021-09-09)
New Hidden pages are displayed by default in the sitemap generated by Hugo and are therefore visible for search engine indexing. You can now turn off this behavior by setting disableSeoHiddenPages=true in your hugo.toml.
2.1.0 (2021-09-07)
0.69.0 This release requires a newer Hugo version.
Change In case the site’s structure contains additional *.md files not part of the site (eg files that are meant to be included by site pages - see CHANGELOG.md in the exampleSite), they will now be ignored by the search.
New Hidden pages are indexed for the site search by default. You can now turn off this behavior by setting disableSearchHiddenPages=true in your hugo.toml.
New If a search term is found in an expand shortcode, the expand will be opened.
New The menu will scroll the active item into view on load.
2.0.0 (2021-08-28)
Change Syntax highlighting was switched to the built in Hugo mechanism. You may need to configure a new stylesheet or decide to roll you own as described on in the Hugo documentation
Change In the predefined stylesheets there was a typo and --MENU-HOME-LINK-HOVERED-color must be changed to --MENU-HOME-LINK-HOVER-color. You don’t need to change anything in your custom color stylesheet as the old name will be used as a fallback.
Change--MENU-HOME-LINK-color and --MENU-HOME-LINK-HOVER-color were missing in the documentation. You should add them to your custom stylesheets if you want to override the defaults.
Change Arrow navigation and children shortcode were ignoring setting for ordersectionsby. This is now changed and may result in different sorting order of your sub pages.
Change If hidden pages are accessed directly by typing their URL, they will be exposed in the menu.
Change A page without a title will be treated as hidden=true.
New You can define the expansion state of your menus in the frontmatter. Please see further documentation for possible values and default behavior.
New New partials for defining pre/post content for menu items and the content. See documentation for further reading.
New Shortcode children with new parameter containerstyle.
New New shortcode include to include arbitrary file content into a page.
1.2.0 (2021-07-26)
New Shortcode expand with new parameter to open on page load.
1.1.0 (2021-07-02)
BreakingMermaid diagrams can now be panned and zoomed. This isn’t configurable yet.
NewMermaid config options can be set in hugo.toml.
1.0.0 (2021-07-01)
0.65.0 The requirement for the Hugo version of this theme is the same as for the Learn theme version 2.5.0 on 2021-07-01.
New Initial fork of the Learn theme based on Learn 2.5.0 on 2021-07-01. This introduces no new features besides a global rename to Relearn and a new logo. For the reasons behind forking the Learn theme, see this comment in the Learn issues.
Requirements
Thanks to the simplicity of Hugo, this page is as empty as this theme needs requirements.
Just download at least version 0.112.4 of the Hugo binary for your OS (Windows, Linux, Mac).
The following steps are here to help you initialize your new website. If you don’t know Hugo at all, we strongly suggest you learn more about it by following this great documentation for beginners.
Create your project
Hugo provides a new command to create a new website.
hugo new site <new_project>
Install the theme
Install the Relearn theme by following this documentation using Hugo’s module system.
If you install the theme from your git repository or GitHub, you have several options.
If you use the head of the main branch, you are using the development version. Usually it is fully functional but can break from time to time. We try to fix newly introduced bugs in this version as soon as possible.
Additionally you can checkout one of the tagged versions. These tagged versions correspond to an official releases from the GitHub repository.
Besides the usual version tags (eg 1.2.3) there are also tags for the main version (eg. 1.2.x), major version (eg. 1.x) and the latest (just x) released version making it easier for you to pin the theme to a certain version.
Basic configuration
When building the website, you can set a theme by using --theme option. However, we suggest you modify the configuration file (hugo.toml) and set the theme as the default. You can also add the [outputs] section to enable the search functionality.
# Change the default theme to be use when building the site with Hugotheme="hugo-theme-relearn"# For search functionality[outputs]home=["HTML","RSS","SEARCH"]
Create your first chapter page
Chapters are pages that contain other child pages. It has a special layout style and usually just contains a chapter name, the title and a brief abstract of the section.
### Chapter 1
# Basics
Discover what this Hugo theme is all about and the core concepts behind it.
renders as
The Relearn theme provides archetypes to create skeletons for your website. Begin by creating your first chapter page with the following command
hugo new --kind chapter basics/_index.md
By opening the given file, you should see the property chapter=true on top, meaning this page is a chapter.
By default all chapters and pages are created as a draft. If you want to render these pages, remove the property draft: true from the metadata.
Create your first content pages
Then, create content pages inside the previously created chapter. Here are two ways to create content in the chapter:
hugo new basics/first-content.md
hugo new basics/second-content/_index.md
Feel free to edit those files by adding some sample content and replacing the title value in the beginning of the files.
Launching the website locally
Launch by using the following command:
hugo serve
Go to http://localhost:1313
You should notice three things:
You have a left-side Basics menu, containing two submenus with names equal to the title properties in the previously created files.
The home page explains how to customize it by following the instructions.
When you run hugo serve, when the contents of the files change, the page automatically refreshes with the changes. Neat!
Build the website
When your site is ready to deploy, run the following command:
hugo
A public folder will be generated, containing all static content and assets for your website. It can now be deployed on any web server.
On top of Hugo’s global configuration options, the Relearn theme lets you define further options unique to the theme in your hugo.toml. The defaults are written in the comments of each option.
Note that some of these options are explained in detail in other sections of this documentation.

Branding
The Relearn theme provides configuration options to change your your site’s colors, favicon and logo. This allows you to easily align your site visuals to your desired style. Most of these options are exposed thru so called color variants.
A color variant lets you customize various visual effects of your site like almost any color, used fonts, color schemes of print, syntax highligtning, Mermaid and the OpenAPI shortcode, etc. It contains of a CSS file and optional configuration options in your hugo.toml.
The Relearn theme ships with a wide set of different color variants. You can use them as-is, copy them over and use them as a starting point for your customizations or just create completely new variants unique to your site. The interactive variant generator may help you with this task.
Once configured in your hugo.toml, you can select them with the variant selector at the bottom of the menu.
Change the Variant (Simple)
Single Variant
Set the themeVariant value to the name of your theme file. That’s it! Your site will be displayed in this variant only.
[params]themeVariant="relearn-light"
Note
Your theme variant file must reside in your site’s static/css directory or in the theme’s static/css directory and the file name must start with theme- and end wit .css. In the above example, the path of your theme file must be static/css/theme-relearn-light.css.
If you want to make changes to a shipped color variant, create a copy in your site’s static/css directory. Don’t edit the file in the theme’s directory!
Multiple Variants
You can also set multiple variants. In this case, the first variant is the default chosen on first view and a variant selector will be shown in the menu footer if the array contains more than one entry.
The theme provides an advanced configuration mode, combining the functionality for multiple variants with the below possibilities of adjusting to your OS settings, logo and syntax highlightning and even more!
Although all options documented here are still working, the advanced configuration options are the recommended way to configure your color variants. See below.
Adjust to OS Settings
You can also cause the site to adjust to your OS settings for light/dark mode. Just set the themeVariant to auto to become an auto mode variant. That’s it.
You can use the auto value with the single or multiple variants option. If you are using multiple variants, you can drop auto at any position in the option’s array, but usually it makes sense to set it in the first position and make it the default.
[params]themeVariant=["auto","red"]
If you don’t configure anything else, the theme will default to use relearn-light for light mode and relearn-dark for dark mode. These defaults are overwritten by the first two non-auto options of your themeVariant option if present.
In the above example, you would end with red for light mode and the default of relearn-dark for dark mode.
If you don’t like that behavior, you can explicitly set themeVariantAuto. The first entry in the array is the color variant for light mode, the second for dark mode.
[params]themeVariantAuto=["learn","neon"]
Change the Favicon
If your favicon is a SVG, PNG or ICO, just drop your image in your site’s static/images/ directory and name it favicon.svg, favicon.png or favicon.ico respectively.
If you want to adjust your favicon according to your OS settings for light/dark mode, add the image files static/images/favicon-light.svg and static/images/favicon-dark.svg to your site’s directory, respectively, corresponding to your file format. In case some of the files are missing, the theme falls back to favicon.svg for each missing file. All supplied favicons must be of the same file format.
If no favicon file is found, the theme will lookup the alternative filename logo in the same location and will repeat the search for the list of supported file types.
If you need to change this default behavior, create a new file layouts/partials/favicon.html in your site’s directory and write something like this:
Create a new file in layouts/partials/logo.html of your site. Then write any HTML you want. You could use an img HTML tag and reference an image created under the static folder, or you could paste a SVG definition!
Note
The size of the logo will adapt automatically.
Syntax Highlightning
If you want to switch the syntax highlighting theme together with your color variant, you need to configure your installation according to Hugo’s documentation and provide a syntax highlighting stylesheet file.
You can use a one of the shipped stylesheet files or use Hugo to generate a file for you. The file must be written to static/css/chroma-<NAME>.css. To use it with your color variant you have to define --CODE-theme: <NAME> in the color variant stylesheet file.
The theme offers a new way to configure theme variants and all of the aspects above inside of a single configuration item. This comes with some features previously unsupported.
Like with the multiple variants option, you are defining your theme variants in an array but now not by simple stringsbut in a table with suboptions.
Again, in this case, the first variant is the default chosen on first view and a variant selector will be shown in the menu footer if the array contains more than one entry.
The identifier option is mandatory and equivalent to the string in the first example. Further options can be configured, see the table below.
Parameter
Name
Default
Notes
identifier
<empty>
Must correspond to the name of a color variant either in your site’s or the theme’s directory in the form static/css/theme-<IDENTIFIER>.css.
name
see notes
The name to be displayed in the variant selector. If not set, the identifier is used in a human readable form.
auto
<empty>
If set, the variant is treated as an auto mode variant. It has the same behavior as the themeVariantAuto option. The first entry in the array is the color variant for light mode, the second for dark mode. Defining auto mode variants with the advanced options has the benefit that you can now have multiple auto mode variants instead of just one with the simple options.
In case you like a shipped variant but only want to tweak some aspects, you have two choices:
Copy and change
You can copy the shipped variant file from the theme’s static/css directory to the site’s static/css directory and either store it with the same name or give it a new name. Edit the settings and save the new file. Afterwards you can use it in your hugo.toml by the choosen name.
Create and import
You can create a new variant file in the site’s static/css directory and give it a new name. Import the shipped variant, add the settings you want to change and save the new file. Afterwards you can use it in your hugo.toml by the choosen name.
For example, you want to use the relearn-light variant but want to change the syntax highlightning schema to the one used in the neon variant. For that, create a new static/css/theme-my-branding.css in your site’s directory and add the following lines:
@import"theme-relearn-light.css";:root{--CODE-theme:learn;/* name of the chroma styleheet file */--CODE-BLOCK-color:rgba(226,228,229,1);/* fallback color for code text */--CODE-BLOCK-BG-color:rgba(40,42,54,1);/* fallback color for code background */}
Afterwards put this in your hugo.toml to use your new variant:
[params]themeVariant="my-branding"
In comparison to copy and change, this has the advantage that you profit from any adjustments to the relearn-light variant but keep your modifications.
Customization
Serving your page from a subfolder
If your site is served from a subfolder, eg. https://example.com/mysite/, you have to set the following lines to your hugo.toml
Without canonifyURLs=true URLs in sublemental pages (like sitemap.xml, rss.xml) will be generated falsly while your HTML files will still work. See https://github.com/gohugoio/hugo/issues/5226.
Serving your page from the filesystem
If you want your page served from the filesystem by using URLs starting with file:// you’ll need the following configuration in your hugo.toml:
relativeURLs=true
The theme will append an additional index.html to all page bundle links by default to make the page be servable from the file system. If you don’t care about the file system and only serve your page via a webserver you can also generate the links without this change by adding this to your hugo.toml
[params]disableExplicitIndexURLs=true
Note
If you want to use the search feature from the file system using an older installation of the theme make sure to change your outputformat for the homepage from the now deprecated JSON to SEARCHas seen below.
Activate search
If not already present, add the following lines in your hugo.toml file.
[outputs]home=["HTML","RSS","SEARCH"]
This will generate a search index file at the root of your public folder ready to be consumed by the Lunr search library. Note that the SEARCH outputformat was named JSON in previous releases but was implemented differently. Although JSON still works, it is now deprecated.
Activate dedicated search page
You can add a dedicated search page for your page by adding the SEARCHPAGE outputformat to your home page by adding the following lines in your hugo.toml file. This will cause Hugo to generate a new file http://example.com/mysite/search.html.
You can access this page by either clicking on the magnifier glass or by typing some search term and pressing ENTER inside of the menu’s search box .
Note
To have Hugo create the dedicated search page successfully, you must not generate the URL http://example.com/mysite/search.html from your own content. This can happen if you set uglyURLs=true in your hugo.toml and defining a Markdown file content/search.md.
To make sure, there is no duplicate content for any given URL of your project, run hugo --printPathWarnings.
Activate print support
You can activate print support to add the capability to print whole chapters or even the complete site. Just add the PRINT output format to your home, section and page in your hugo.toml as seen below:
This will add a little printer icon in the top bar. It will switch the page to print preview when clicked. You can then send this page to the printer by using your browser’s usual print functionality.
Note
The resulting URL will not be configured ugly in terms of Hugo’s URL handling even if you’ve set uglyURLs=true in your hugo.toml. This is due to the fact that for one mime type only one suffix can be configured.
Nevertheless, if you’re unhappy with the resulting URLs you can manually redefine outputFormats.PRINT in your own hugo.toml to your liking.
Home Button Configuration
If the disableLandingPageButton option is set to false, a Home button will appear
on the left menu. It is an alternative for clicking on the logo. To edit the
appearance, you will have to configure the landingPageName for the defined languages:
You can add social media meta tags for the Open Graph protocol and Twitter Cards to your site. These are configured as mentioned in the Hugo docs.
Change the Menu Width
The menu width adjusts automatically for different screen sizes.
Name
Screen Width
Menu Width
S
< 48rem
0
M
48rem - 60rem
14.375rem
L
>= 60rem
18.75rem
The values for the screen width breakpoints aren’t configurable.
If you want to adjust the menu width you can define the following CSS variables in your custom-header.html. Note that --MENU-WIDTH-S doesn’t exist as the menu is always hidden for small screen sizes.
Certain shortcodes make use of additional JavaScript files. The theme only loads these dependencies if the shortcode is used. To do so correctly the theme adds management code in various files.
You can you use this mechanism in your own shortcodes. Say you want to add a shortcode myshortcode that also requires the jquery JavaScript library.
Write the shortcode file layouts/shortcodes/myshortcode.html and add the following line
Add the dependency loader file layouts/partials/dependencies/myshortcode.html. The loader file will be appended to your header or footer, dependend on the location setting in your hugo.toml.
the name setting in your hugo.toml must match the key (that needs to be prefixed with a has) you used for the store in your layouts/shortcodes/myshortcode.html.
the key on params.relearn.dependencies in your hugo.toml must match the base file name of your loader file.
See the math, mermaid and openapi shortcodes for examples.
Output Formats
Certain parts of the theme can be changed for support of your own output formats. Eg. if you define a new output format PLAINTEXT in your hugo.toml, you can add a file layouts/partials/header.plaintext.html to change the way, the page header should look like for that output format.
React to Variant Switches in JavaScript
Once a color variant is fully loaded, either initially or by switching the color variant manually with the variant selector, the custom event themeVariantLoaded on the document will be dispatched. You can add an event listener and react to changes.
The Relearn theme has been built to be as configurable as possible by defining multiple partials
In themes/hugo-theme-relearn/layouts/partials/, you will find all the partials defined for this theme. If you need to overwrite something, don’t change the code directly. Instead follow this page. You’d create a new partial in the layouts/partials folder of your local project. This partial will have the priority.
body.html: the body of the page. The body may contain of one or many articles. See output-formats
article.html: the output for a single article, can contain elements around your content. See output-formats
menu.html: left menu. Not meant to be overwritten
search.html: search box. Not meant to be overwritten
custom-header.html: custom headers in page. Meant to be overwritten when adding CSS imports. Don’t forget to include style HTML tag directive in your file.
custom-footer.html: custom footer in page. Meant to be overwritten when adding JavaScript. Don’t forget to include javascript HTML tag directive in your file.
favicon.html: the favicon
heading.html: side-wide configuration to change the pages title headings.
heading-pre.html: side-wide configuration to prepend to pages title headings. If you override this, it is your responsibility to take the page’s headingPre setting into account.
heading-post.html: side-wide configuration to append to pages title headings. If you override this, it is your responsibility to take the page’s headingPost setting into account.
logo.html: the logo, on top left hand corner
meta.html: HTML meta tags, if you want to change default behavior
menu-pre.html: side-wide configuration to prepend to menu items. If you override this, it is your responsibility to take the page’s menuPre setting into account.
menu-post.html: side-wide configuration to append to menu items. If you override this, it is your responsibility to take the page’s menuPost setting into account.
menu-footer.html: footer of the the left menu
toc.html: table of contents
content.html: the content page itself. This can be overridden if you want to display page’s meta data above or below the content.
content-header.html: header above the title, has a default implementation but you can overwrite it if you don’t like it.
content-footer.html: footer below the content, has a default implementation but you can overwrite it if you don’t like it.
Stylesheet generator
This interactive tool may help you to generate your own color variant stylesheet.
To get started, first select a color variant from the variant selector in the lower left sidebar that fits you best as a starting point.
The graph is interactive and reflect the current colors. You can click on any of the colored boxes to adjust the respective color. The graph and the page will update accordingly.
The arrowed lines reflect how colors are inherited thru different parts of the theme if the descendent isn’t overwritten. If you want to delete a color and let it inherit from its parent, just delete the value from the input field.
To better understand this select the neon variant and modify the different heading colors. There, colors for the heading h2, h3 and h4 are explicitly set. h5 is not set and inherits its value from h4. h6 is also not set and inherits its value from h5.
Once you’ve changed a color, the variant selector will show a “My custom variant” entry and your changes are stored in the browser. You can browse to other pages and even close the browser without losing your changes.
Once you are satisfied, you can download the new variants file and copy it into your site’s static/css directory. Afterwards you have to adjust the themeVariant parameter in your hugo.toml to your chosen file name.
Eg. if your new variants file is named theme-my-custom-variant.css, you have to set themeVariant='my-custom-variant' to use it.
Graph
Topbar Modification
The theme comes with a reasonably configured topbar.
Nevertheless, your requirements may differ from this configuration. Luckily the theme got you covered as the themebar, its buttons and the functionality behind these buttons is fully configurable by you.
Tip
All mentioned file names below can be clicked and show you the implementation for a better understanding.
Areas
The default configuration comes with three predefined areas that may contain an arbitrary set of buttons.
end: shown on the opposite breadcrumb side in comparison to the start area
more: shown when pressing the more button in the topbar
While you can not add additional areas in the topbar, you are free to configure addtional buttons that behave like the more button, providing further user defined areas.
Buttons
The theme ships with the following predefined buttons (from left to right in the screenshot)
sidebar: opens the sidebar flyout if in mobile layout
Not all buttons are displayed at every given time. This is configurable (see below if interested).
Redefining Areas
Each predefined area and button comes in their own file. By that it is easy for you to overwrite an area file in your installation reusing only the buttons you like.
Eg. you can redefine the predefined end area by adding the file layouts/partials/topbar/area/end.html in your installation (not in the theme itself) to remove all but the more button.
The below example sets an explicit value for the onempty parameter, overriding the specific default value for this button (these defaults vary depending on the button). The parameter causes the more button to always be displayed instead of hiding once its content is empty.
The theme distingushies between two types of buttons:
button: a clickable button that either browses to another site, triggers a user defined script or opens an overlay containing user defined content
area-button: the template for the more button, to define your own area overlay buttons
Button Parameter
Screen Widths and Actions
Depending on the screen width you can configure how the button should behave. Screen width is divided into three classes:
s: (controlled by the onwidths parameter) mobile layout where the menu sidebar is hidden
m: (controlled by the onwidthm parameter) desktop layout with visible sidebar while the content area width still resizes
l: (controlled by the onwidthl parameter) desktop layout with visible sidebar once the content area reached its maximum width
For each width class, you can configure one of the following actions:
show: the button is displayed in its given area
hide: the button is removed
area-XXX: the button is moved from its given area into the area XXX; eg. this is used to move buttons to the more area overlay in the mobile layout
Hiding and Disabling Stuff
While hiding a button dependend on the screen size can be configured with the above described hide action, you may want to hide the button on certain other conditions aswell.
For example, the print button in its default configuration should only be displayed if print support was configured. This is done in your button template by checking the conditions first before displaying the button (see layouts/partials/topbar/button/print.html).
This parameter can have one of the following values:
disable: the button displayed in disabled state if the overlay is empty
hide: the button is removed if the overlay is empty
If you want to disable a button containing no overlay, this can be achieved by an empty href parameter. An example can be seen in the prev button (see layouts/partials/topbar/button/prev.html) where the URL for the previous site may be empty.
For displaying an area in the button’s overlay, see Area-Button.

Create your project
The following steps are here to help you initialize your new website. If you don’t know Hugo at all, we strongly suggest you to train by following great documentation for beginners.
Hugo provides a new command to create a new website.
hugo new site <new_project>
The Relearn theme provides archetypes to help you create this kind of pages.
Frontmatter
Each Hugo page has to define a frontmatter in toml, yaml or json. This site will use toml for documentation in all cases.

Some Detailed Examples
Add Icon to a Menu Entry
In the page frontmatter, add a menuPre param to insert any HTML code before the menu label. The example below uses the GitHub icon.
Hugo provides a flexible way to handle order for your pages.
The simplest way is to set weight parameter to a number.
+++title="My page"weight=5+++
Using a Custom Title for Menu Entries
By default, the Relearn theme will use a page’s title attribute for the menu item (or linkTitle if defined).
But a page’s title has to be descriptive on its own while the menu is a hierarchy.
We’ve added the menuTitle parameter for that purpose:
For example (for a page named content/install/linux.md):
+++title="Install on Linux"menuTitle="Linux"+++
Override Expand State Rules for Menu Entries
You can change how the theme expands menu entries on the side of the content with the alwaysopen setting on a per page basis. If alwaysopen=false for any given entry, its children will not be shown in the menu as long as it is not necessary for the sake of navigation.
The theme generates the menu based on the following rules:
all parent entries of the active page including their siblings are shown regardless of any settings
immediate children entries of the active page are shown regardless of any settings
if not overridden, all other first level entries behave like they would have been given alwaysopen=false
if not overridden, all other entries of levels besides the first behave like they would have been given alwaysopen=true
all visible entries show their immediate children entries if alwaysopen=true; this proceeds recursively
all remaining entries are not shown
You can see this feature in action on the example page for children shortcode and its children pages.
Disable Section Pages
You may want to structure your pages in a hierachical way but don’t want to generate pages for those sections? The theme got you covered.
To stay with the initial example: Suppose you want level-one appear in the sidebar but don’t want to generate a page for it. So the entry in the sidebar should not be clickable but should show an expander.
For this, open content/level-one/_index.md and add the following frontmatter
+++collapsibleMenu=true# this adds the expander to the menu entry if not already set in your hugo.toml[_build]render="never"# no page will be generated so the page does not have a url+++
Archetypes
Using the command: hugo new [relative new content path], you can start a content file with the date and title automatically set. While this is a welcome feature, active writers need more: archetypes. These are preconfigured skeleton pages with default frontmatter.
The Relearn theme defines some few archetypes of pages but you are free to define new ones to your liking. All can be used at any level of the documentation, the only difference being the layout of the content.
Predefined Archetypes
Home
A Home page is the starting page of your project. It’s best to have only one page of this kind in your project.
To create a home page, run the following command
hugo new --kind home _index.md
This leads to a file with the following content
+++
archetype = "home"
title = "{{ replace .Name "-" " " | title }}"
+++
Lorem Ipsum.
Chapter
A Chapter displays a page meant to be used as introduction for a set of child pages. Commonly, it contains a simple title and a catch line to define content that can be found below it.
To create a chapter page, run the following command
hugo new --kind chapter <name>/_index.md
This leads to a file with the following content
+++
archetype = "chapter"
title = "{{ replace .Name "-" " " | title }}"
weight = X
+++
Lorem Ipsum.
Replace the X with a number. Because this number will be used to generate the subtitle of the chapter page, set the number to a consecutive value starting at 1 for each new chapter level.
Default
A Default page is any other content page. If you set an unknown archetype in your frontmatter, this archetype will be used to generate the page.
To create a default page, run either one of the following commands
hugo new <chapter>/<name>/_index.md
or
hugo new <chapter>/<name>.md
This leads to a file with the following content
+++
title = "{{ replace .Name "-" " " | title }}"
weight = X
+++
Lorem Ipsum.
Replace the X with a number or delete the whole weight parameter entirely.
Self defined Archetypes
If you are in need of further archetypes you can define your own or even redefine existing ones.
Template
Define a template file in your project at archetypes/<kind>.md and make sure it has at least the frontmatter parameter for that archetype like
+++
archetype = "<kind>"
+++
Afterwards you can generate new content files of that kind with the following command
hugo new --kind <kind> <name>/_index.md
Partials
To define how your archetypes are rendered, define corresponding partial files in your projects directory layouts/partials/archetypes/<kind>.
If you use an unknown archetype in your frontmatter, the default archetype will be used to generate the page.
Related to each archetype, several hook partial files in the form of <hook>.html can be given inside each archetype directory. If a partial for a specific hook is missing, no output is generated for this hook.
The following hooks are used:
Name
Notes
styleclass
Defines a set of CSS classes to be added to the HTML’s <main> element. You can use these classes to define own CSS rules in your custom-header.html
article
Defines the HTML how to render your content
Take a look at the existing archetypes of this theme to get an idea how to utilize it.
Output formats
Each hook file can be overridden of a specific output format. Eg. if you define a new output format PLAINTEXT in your hugo.toml, you can add a file layouts/partials/archetypes/default.plaintext.html to change the way how normal content is written for that output format.
Let’s face it: Writing content for the web is tiresome. WYSIWYG editors help alleviate this task, but they generally result in horrible code, or worse yet, ugly web pages.
Markdown is a better way to write HTML, without all the complexities and ugliness that usually accompanies it.
Some of the key benefits are:
Markdown is simple to learn, with minimal extra characters so it’s also quicker to write content.
Less chance of errors when writing in Markdown.
Produces valid HTML output.
Keeps the content and the visual display separate, so you cannot mess up the look of your site.
Write in any text editor or Markdown application you like.
Markdown is a joy to use!
John Gruber, the author of Markdown, puts it like this:
The overriding design goal for Markdown’s formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions. While Markdown’s syntax has been influenced by several existing text-to-HTML filters, the single biggest source of inspiration for Markdown’s syntax is the format of plain text email.
John Gruber
Without further delay, let us go over the main elements of Markdown and what the resulting HTML looks like:
In Markdown your content usually spans the whole available document width. This is called a block. Blocks are always separated by whitespace to their adjacent blocks in the resulting document.
Any text not starting with a special sign is written as normal, plain text paragraph block and must be separated to its adjacent blocks by empty lines.
Lorem ipsum dolor sit amet, graecis denique ei vel, at duo primis mandamus.
Et legere ocurreret pri, animal tacimates complectitur ad cum. Cu eum inermis inimicus efficiendi. Labore officiis his ex, soluta officiis concludaturque ei qui, vide sensibus vim ad.
Result
Lorem ipsum dolor sit amet, graecis denique ei vel, at duo primis mandamus.
Et legere ocurreret pri, animal tacimates complectitur ad cum. Cu eum inermis inimicus efficiendi. Labore officiis his ex, soluta officiis concludaturque ei qui, vide sensibus vim ad.
Headings
A good idea is to structure your content using headings and subheadings. HTML-headings from h1 through h6 are constructed with a # for each level.
In Hugo you usually don’t use h1 as this is generated by your theme and you should only have one such element in a document.
To further structure your content you can add horizontal rules. They create a “thematic break” between paragraph blocks. In Markdown, you can create it with three consecutive dashes ---.
Lorem ipsum dolor sit amet, graecis denique ei vel, at duo primis mandamus.

Text substitution
This Markdown dialect supports an extension to combine multiple punctuation characters to single typographic entities. This will only be applied to text outside of code blocks or inline code.
Double quotes `"` and single quotes `'` of enclosed text are replaced by **"double curly quotes"** and **'single curly quotes'**.
Double dashes `--` and triple dashes `---` are replaced by en-dash **--** and em-dash **---** entities.
Double arrows pointing left `<<` or right `>>` are replaced by arrow **<<** and **>>** entities.
Three consecutive dots `...` are replaced by an ellipsis **...** entity.
Result
Double quotes " and single quotes ' of enclosed text are replaced by “double curly quotes” and ‘single curly quotes’.
Double dashes -- and triple dashes --- are replaced by en-dash – and em-dash — entities.
Double arrows pointing left << or right >> are replaced by arrow « and » entities.
Three consecutive dots ... are replaced by an ellipsis … entity.
Lists
Unordered
You can write a list of items in which the order of the items does not explicitly matter.
It is possible to nest lists by indenting an item for the next sublevel.
You may use any of -, * or + to denote bullets for each list item but should not switch between those symbols inside one whole list.
- Lorem ipsum dolor sit amet

Ordered
You can create a list of items in which the order of items does explicitly matter.
It is possible to nest lists by indenting an item for the next sublevel.
Markdown will automatically number each of your items consecutively. This means, the order number you are providing is irrelevant.
1. Lorem ipsum dolor sit amet
3. Consectetur adipiscing elit
1. Integer molestie lorem at massa
7. Facilisis in pretium nisl aliquet
99. Nulla volutpat aliquam velit

Definitions
This Markdown dialect supports an extension to add definition lists. Definition lists are made of terms and definitions of these terms, much like in a dictionary.
A definition list in Markdown Extra is made of a single-line term followed by a colon and the definition for that term. You can also associate more than one term to a definition.
If you add empty lines around the definition terms, additional vertical space will be generated. Also multiple paragraphs are possible
Apple

: An American computer company.
Orange
: The fruit of an evergreen tree of the genus Citrus.
You can make juice out of it.
: A telecommunication company.

Code
Inline Code
Inline snippets of code can be wrapped with backticks `.
In this example, `<div></div>` is marked as code.
Result
In this example, <div></div> is marked as code.
Indented Code Block
A simple code block can be generated by indenting several lines of code by at least two spaces.
Be impressed by my advanced code:
// Some comments

line 2 of code
line 3 of code
Result

Fenced Code Block
If you want to gain more control of your code block you can enclose your code by at least three backticks ``` a so called fence.
In GFM (GitHub Flavored Markdown) you can also add a language specifier directly after the opening fence, ```js, and syntax highlighting will automatically be applied according to the selected language in the rendered HTML.
In GFM (GitHub Flavored Markdown) you can create tables by adding pipes as dividers between each cell, and by adding a line of dashes (also separated by bars) beneath the header. Note that the pipes do not need to be vertically aligned.

Links
Autolink
In GFM (GitHub Flavored Markdown) absolute URLs will automatically be converted into a link.
Links can be simplyfied for recurring reuse by using a reference ID to later define the URL location. This simplyfies writing if you want to use a link more than once in a document.
[Example][somelinkID]
[somelinkID]: https://example.com "Go to example domain"
Footnotes work mostly like reference-style links. A footnote is made of two things, a marker in the text that will become a superscript number and a footnote definition that will be placed in a list of footnotes.
Usually the list of footnotes will be shown at the end of your document. If we use a footnote in a notice box it will instead be listed at the end of its box.
Footnotes can contain block elements, which means that you can put multiple paragraphs, lists, blockquotes and so on in a footnote. It works the same as for list items, just indent the following paragraphs by four spaces in the footnote definition.
That's some text with a footnote[^1]
[^1]: And that's the footnote.
That's some more text with a footnote.[^someid]
[^someid]:
Anything of interest goes here.
Blue light glows blue.
Images can also be linked by reference ID to later define the URL location. This simplyfies writing if you want to use an image more than once in a document.

Image Effects
This theme allows additional non-standard formatting by setting query parameter at the end of the image URL. The default behavior is configurable thru your hugo.toml or frontmatter parameter.
Resizing
Add query parameter width and/or height to the link image to resize the image. Values are CSS values (default is auto).
If you want to wrap an image in a link and lightbox=true is your default setting, you have to explicitly disable the lightbox to avoid it to hijacking your link like:
As you can see in the above example, the bg-white parameter is not initially supported in the themes default settings. Nevertheless you are free to define arbitrary parameter by just adding them to the URL query parameter or set them in your hugo.toml or pages frontmatter.
Note
If no extended parameter like bg-white in the example is set on the URL, a class="nobg-white" in the HTML will only be generated if a default value was set in the hugo.toml or pages frontmatter.
Menu extra shortcuts
You can define additional menu entries or shortcuts in the navigation menu without any link to content.
Basic configuration
Edit the website configuration hugo.toml and add a [[menu.shortcuts]] entry for each link your want to add.
By default, shortcuts are preceded by a title. This title can be disabled by setting disableShortcutsTitle=true.
However, if you want to keep the title but change its value, it can be overridden by changing your local i18n translation string configuration.
For example, in your local i18n/en.toml file, add the following content
When using a multilingual website, you can set different menus for each language. In the hugo.toml file, prefix your menu configuration by Languages.<language-id>.
If you have shortcuts to pages inside of your project and you don’t want them to show up in page menu section, you have two choices:
Make the page file for the shortcut a headless branch bundle (contained in its own subdirectory and called _index.md) and add the following frontmatter configuration to the file (see exampleSite’s content/showcase/_index.en.md). This causes its content to not be ontained in the sitemap.
Store the page file for the shortcut below a parent headless branch bundle and add the following frontmatter to he parent (see exampleSite’s content/more/_index.en.md).
# title = "More" ### ATTENTION: Don't give this page a title as this will cause it to be in the breadcrumbs - a thing you most likely don't want[_build]render="never"list="never"publishResources=false
In this case, the file itself can be a branch bundle, leaf bundle or simple page (see exampleSite’s content/more/credits.en.md). This causes its content to be contained in the sitemap.
title="Credits"
Multilingual and i18n
The Relearn theme is fully compatible with Hugo multilingual mode.
Available languages: Arabic, Simplified Chinese, Traditional Chinese, Czech, Dutch, English, Finnish, French, German, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Polish, Portuguese, Russian, Spanish, Swahili, Turkish, Vietnamese. Feel free to contribute!
Full support for languages written right to left
Automatic menu generation from multilingual content
For example with current English and Piratized English website.
Note
Make sure your default language is defined as the first one in the [languages] array, as the theme needs to make assumptions on it
# English is the default languagedefaultContentLanguage="en"[languages][languages.en]title="Hugo Relearn Theme"weight=1languageName="English"[languages.pir]title="Cap'n Hugo Relearrrn Theme"weight=2languageName="Arrr! Pirrrates"
Then, for each new page, append the id of the language to the file.
Single file my-page.md is split in two files:
in English: my-page.md
in Piratized English: my-page.pir.md
Single file _index.md is split in two files:
in English: _index.md
in Piratized English: _index.pir.md
Info
Be aware that only translated pages are displayed in menu. It’s not replaced with default language content.
Tip
Use slug frontmatter parameter to translate urls too.
Search
In case each page’s content is written in one single language only, the above configuration will already configure the site’s search functionality correctly.
Warning
Although the theme supports a wide variety of supported languages, the site’s search via the Lunr search library does not.
You’ll see error reports in your browsers console log for each unsupported language. Currently unsupported are:
Czech
Indonesian
Polish
Swahili
Search with mixed language support
In case your page’s content contains text in multiple languages (e.g. you are writing a Russian documentation for your english API), you can add those languages to your hugo.toml to broaden search.
[params]additionalContentLanguage=["en"]
As this is an array, you can add multiple additional languages.
Note
Keep in mind that the language code required here, is the base language code. E.g. if you have additional content in zh-CN, you have to add just zh to this parameter.
Overwrite translation strings
Translations strings are used for common default values used in the theme (Edit button, Search placeholder and so on). Translations are available in English and Piratized English but you may use another language or want to override default values.
To override these values, create a new file in your local i18n folder i18n/<idlanguage>.toml and inspire yourself from the theme themes/hugo-theme-relearn/i18n/en.toml
Disable language switching
Switching the language in the browser is a great feature, but for some reasons you may want to disable it.
Just set disableLanguageSwitchingButton=true in your hugo.toml
[params]# When using multilingual website, disable the switch language button.disableLanguageSwitchingButton=true
The tags are displayed at the top of the page in alphabetical order.
The categories are displayed at the bottom of the page in alphabetical order in the default implementation of the theme but can be customized by providing your own content-footer.html partial.
Each item is a link to a taxonomy page displaying all the articles with the given term.
List all the tags
In the hugo.toml file you can add a shortcut to display all the tags and categories
If you define custom taxonomies and want to display a list of them somewhere on your page (often in the layouts/partials/content-footer.html) you can call a partial that does the job for you:
The plural name of the taxonomy to display as used in your frontmatter.
class
<empty>
Additional CSS classes set on the outermost generated HTML element.
If set to tags you will get the visuals for displaying the tags taxonomy, otherwise it will be a simple list of links as for the categories taxonomy.
style
primary
The style scheme used if class is tags.
- by severity: info, note, tip, warning - by brand color: primary, secondary, accent - by color: blue, green, grey, orange, red - by special color: default, transparent, code
color
see notes
The CSS color value to be used if class is tags. If not set, the chosen color depends on the style. Any given value will overwrite the default.
- for severity styles: a nice matching color for the severity - for all other styles: the corresponding color
Hugo uses Markdown for its simple content format. However, there are a lot of things that Markdown doesn’t support well. You could use pure HTML to expand possibilities.
But this happens to be a bad idea. Everyone uses Markdown because it’s pure and simple to read even non-rendered. You should avoid HTML to keep it as simple as possible.
To avoid this limitations, Hugo created shortcodes. A shortcode is a simple snippet inside a page.
The Relearn theme provides multiple shortcodes on top of existing ones.
Since Hugo 0.112.0 this only works for leaf bundles. Branch bundles and simple pages must be switched to leaf bundles or you are currently locked to a Hugo version < 0.112.0.
Usage
While the examples are using shortcodes with named parameter you are free to also call this shortcode from your own partials.
- by severity: info, note, tip, warning - by brand color: primary, secondary, accent - by color: blue, green, grey, orange, red - by special color: default, transparent, code
color
see notes
The CSS color value to be used. If not set, the chosen color depends on the style. Any given value will overwrite the default.
- for severity styles: a nice matching color for the severity - for all other styles: the corresponding color
title
see notes
Arbitrary text for the box title. Depending on the style there may be a default title. Any given value will overwrite the default.
- for severity styles: the matching title for the severity - for all other styles: Attachments
If you want no title for a severity style, you have to set this parameter to " " (a non empty string filled with spaces)
icon
see notes
Font Awesome icon name set to the left of the title. Depending on the style there may be a default icon. Any given value will overwrite the default.
- for severity styles: a nice matching icon for the severity - for all other styles: paperclip
If you want no icon, you have to set this parameter to " " (a non empty d with spaces)
sort
asc
Sorting the output in ascending or descending order.
pattern
.*
A regular expressions, used to filter the attachments by file name. For example:
- to match a file suffix of ‘jpg’, use .*\.jpg (not *.\.jpg) - to match file names ending in jpg or png, use .*\.(jpg|png)
Setup
Single language
The shortcode lists files found in a specific folder. The name of the folder depends on your page type (either branch bundle, leaf bundle or page).
If your page is a leaf bundle, attachments must be placed in a nested index.files folder, accordingly.
content
_index.md
page
_index.md
_index.files
attachment.pdf
If your page is a branch bundle, attachments must be placed in a nested _index.files folder, accordingly.
Warning This is only available for Hugo < 0.112.0
content
_index.md
page
index.md
index.files
attachment.pdf
For simple pages, attachments must be placed in a folder named like your page and ending with .files.
Warning This is only available for Hugo < 0.112.0
content
_index.md
page.files
attachment.pdf
page.md
Multilingual
Be aware that if you use a multilingual website, you will need to have as many folders as languages and the language code must be part of the folder name.
Eg. for a site in English and Piratish:
content
index.en.md
index.pir.md
page
index.en.md
index.pir.md
index.en.files
attachment.pdf
index.pir.files
attachment.pdf
Examples
Custom Title, List of Attachments Ending in pdf or mp4
For further examples for style, color, title and icon, see the notice shortcode documentation. The parameter are working the same way for both shortcodes, besides having different defaults.

When true shows a short text under each page in the list. When no description or summary exists for the page, the first 70 words of the content is taken - read more info about summaries on gohugo.io.
depth
1
The depth of descendants to display. For example, if the value is 2, the shortcode will display two levels of child pages. To get all descendants, set this value to a high number eg. 999.
This only works in modern browsers flawlessly. While Internet Explorer 11 has issues in displaying it, the functionality still works.
Usage
While the examples are using shortcodes with named parameter you are free to use positional as well or also call this shortcode from your own partials.

Highlight
The highlight shortcode renders your code with a syntax highlighter.
1print("Hello World!")
Usage
This shortcode is fully compatible with Hugo’s highlight shortcode but offers some extensions.
It is called interchangeably in the same way as Hugo’s own shortcode providing positional parameter or by simply using codefences.
You are free to also call this shortcode from your own partials. In this case it resembles Hugo’s highlight function syntax if you call this shortcode as a partial using compatiblity syntax.
While the examples are using shortcodes with named parameter it is recommended to use codefences instead. This is because more and more other software supports codefences (eg. GitHub) and so your markdown becomes more portable.

Font Awesome icon name to be displayed. It will be displayed in the text color of its according context.
Finding an icon
Browse through the available icons in the Font Awesome Gallery. Notice that the free filter is enabled, as only the free icons are available by default.
Once on the Font Awesome page for a specific icon, for example the page for the heart, copy the icon name and paste into the Markdown content.
Customising Icons
Font Awesome provides many ways to modify the icon
Change color (by default the icon will inherit the parent color)
While the shortcode simplifies using standard icons, the icon customization and other advanced features of the Font Awesome library require you to use HTML directly. Paste the <i> HTML into markup, and Font Awesome will load the relevant icon.

Include
The include shortcode includes other files from your project inside of the current page.
Usage
While the examples are using shortcodes with named parameter you are free to use positional aswell or also call this shortcode from your own partials.
When true and the included file contains headings, the first heading will be hidden. This comes in handy, eg. if you include otherwise standalone Markdown files.

Et Cetera (English: /ɛtˈsɛtərə/), abbreviated to etc., etc, et cet., is a Latin expression that is used in English to mean “and other similar things”, or “and so forth” ↩︎
Math
The math shortcode generates beautiful formatted math and chemical formulae using the MathJax library.
While the examples are using shortcodes with named parameter it is recommended to use codefences instead. This is because more and more other software supports Math codefences (eg. GitHub) and so your markdown becomes more portable.
You are free to also call this shortcode from your own partials.
MathJax is configured with default settings. You can customize MathJax’s default settings for all of your files thru a JSON object in your hugo.toml or override these settings per page thru your pages frontmatter.
The JSON object of your hugo.toml / frontmatter is forwarded into MathJax’s configuration object.
Inline math is generated if you use a single `$` as a delimiter around your formulae: {{<math>}}$\sqrt{3}${{</math>}}
Inline math is generated if you use a single $ as a delimiter around your formulae:
$\sqrt{3}$
Blocklevel Math with Right Alignment
If you delimit your formulae by two consecutive `$$` it generates a new block.
{{<mathalign="right">}}
$$\left( \sum_{k=1}^n a_k b_k \right)^2 \leq \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)$$
{{</math>}}
If you delimit your formulae by two consecutive $$ it generates a new block.

Your Mermaid graph.
Configuration
Mermaid is configured with default settings. You can customize Mermaid’s default settings for all of your files thru a JSON object in your hugo.toml, override these settings per page thru your pages frontmatter or override these setting per diagramm thru diagram directives.
The JSON object of your hugo.toml / frontmatter is forwarded into Mermaid’s mermaid.initialize() function.
The theme setting can also be set by your used color variant. This will be the sitewide default and can - again - be overridden by your settings in hugo.toml, frontmatter or diagram directives.

The URL to the OpenAPI specification file. This can be relative to the URL of your page if it is a leaf or branch bundle.
Note
If you want to print out (or generate a PDF) from your OpenAPI documentation, don’t initiate printing directly from the page because the elements are optimized for interactive usage in a browser.
Instead, open the print preview in your browser and initiate printing from that page. This page is optimized for reading and expands most of the available sections.
Example
Using Local File

SiteParam
The siteparam shortcode prints values of site params.
Usage
While the examples are using shortcodes with named parameter you are free to use positional aswell or call this shortcode from your own partials.
The style scheme used for the tab. If you don’t set a style and you display a single code block inside of the tab, its default styling will adapt to that of a code block. Otherwise default is used.

A tab can not only contain code but arbitrary text. In this case text and code will get a margin.
printf("Hello World!");
Understanding style and color Behavior
The style parameter affects how the color parameter is applied.
{{<tabs>}}{{%tabtitle="just colored style"style="blue"%}}The`style`parameterissettoacolorstyle.Thiswillsetthebackgroundtoalighterversionofthechosenstylecolorasconfiguredinyourthemevariant.{{%/tab%}}{{%tabtitle="just color"color="blue"%}}Onlythe`color`parameterisset.ThiswillsetthebackgroundtoalighterversionofthechosenCSScolorvalue.{{%/tab%}}{{%tabtitle="default style and color"style="default"color="blue"%}}The`style`parameteraffectshowthe`color`parameterisapplied.The`default`stylewillsetthebackgroundtoyour`--MAIN-BG-color`asconfiguredforyourthemevariantresemblingthedefaultstylebutwithdifferentcolor.{{%/tab%}}{{%tabtitle="just severity style"style="info"%}}The`style`parameterissettoaseveritystyle.Thiswillsetthebackgroundtoalighterversionofthechosenstylecolorasconfiguredinyourthemevariantandalsoaffectsthechosenicon.{{%/tab%}}{{%tabtitle="severity style and color"style="info"color="blue"%}}The`style`parameteraffectshowthe`color`parameterisapplied.ThiswillsetthebackgroundtoalighterversionofthechosenCSScolorvalueandalsoaffectsthechosenicon.{{%/tab%}}{{</tabs>}}
The style parameter is set to a color style.
This will set the background to a lighter version of the chosen style color as configured in your theme variant.
Only the color parameter is set.
This will set the background to a lighter version of the chosen CSS color value.
The style parameter affects how the color parameter is applied.
The default style will set the background to your --MAIN-BG-color as configured for your theme variant resembling the default style but with different color.
The style parameter is set to a severity style.
This will set the background to a lighter version of the chosen style color as configured in your theme variant and also affects the chosen icon.
The style parameter affects how the color parameter is applied.
This will set the background to a lighter version of the chosen CSS color value and also affects the chosen icon.
Tabs
The tabs shortcode displays arbitrary content in an unlimited number of tabs.
This comes in handy eg. for providing code snippets for multiple languages.
If you just want a single tab you can instead call the tab shortcode standalone.
hello.
print("Hello World!")
echo"Hello World!"
printf("Hello World!");
Usage
While the examples are using shortcodes with named parameter you are free to also call this shortcode from your own partials.
See the tab shortcode for a description of the parameter for nested tabs.
Arbitrary name of the group the tab view belongs to.
Tab views with the same groupid sychronize their selected tab. The tab selection is restored automatically based on the groupid for tab view. If the selected tab can not be found in a tab group the first tab is selected instead.
This sychronization applies to the whole site!
style
<empty>
Sets a default value for every contained tab. Can be overridden by each tab. See the tab shortcode for possible values.
color
<empty>
Sets a default value for every contained tab. Can be overridden by each tab. See the tab shortcode for possible values.
In case you want to nest tab views, the parent tab that contains nested tab views needs to be declared with {{< tab >}} instead of {{% tab %}}. Note, that in this case it is not possible to put markdown in the parent tab.
You can also set style and color parameter for all tabs and overwrite them on tab level. See the tab shortcode for possible values.
