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.

• 0.121.0 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.

6.0.0.beta (XXXX-XX-XX)

• Breaking This release requires you to move your self-defined variant (theme-*.css) and chroma stylesheets (chroma-*.css) from static/css to assets/css.

  This was necessary to avoid permission errors on build if running in certain Unix configurations.

  In addition it is not allowed anymore to @import your chroma stylesheet from inside of your variant stylesheet.

  Say, your chroma stylesheet is named chroma-monokai.css, you have to add the following inside your variant stylesheet:

  --CODE-theme: monokai;

• Breaking Support for Internet Explorer 11 was finally dropped.

• Change Removing support for Internet Explorer 11 allowed to upgrade Font Awesome to version 6.5.2.

  You may experience slight changes for some icons. In addition you have additional ~1700 icons to chose from.

• Change The include shortcode is now able to resolve links to resources as well as to files in the file system (the old behavior). You can configure to generate warnings or errors during build by setting include.errorlevel to either warning or error in your hugo.toml if a path can not be resolved.

• New Math is now usable without enclosing it in a shortcode or codefence by using Hugo’s passthrough configuration.

• New Translation into Romanian.

5.27.0 (2024-04-07)

• 0.121.0 This release requires a newer Hugo version.

• Change If the theme is configured to generate warnings or errors during build by setting image.errorlevel to either warning or error in your hugo.toml, it will now also generate output if a link fragment is not found in the target page.

• Change The dependency loader was made more versatile.

  The configuration in your hugo.toml does not require the location parameter anymore. If you still use it, the theme will work as before but will generate a warning. So you don’t need to change anything, yet.

  With the new mechanism, your dependency loader now receives an additional location parameter instead that you can query to inject your dependencies in the desired location.

  By that you can now call the dependency mechanism in your own overriden partials by giving it a distinct location parameter. In addition your injected files can now be spread to multiple locations which wasn’t previously possible.

• New Additional styling was added for the native HTML elements <mark> and <kbd>. To use them you must allow the usage of HTML in your hugo.toml. The Markdown documentation was enhanced for this.

• New You now can scroll forward and backward through all headings of a page by using ALT 🡑 and ALT 🡓. This also works for the PRINT output format.

• New The breadcrumbs used in the topbar, search results and the taxonomy term lists are now using the pages frontmatter linktitle instead of title if set.

5.26.0 (2024-03-18)

• New The lazy loading of images is now configurable by using the new lazy image effect. The default value hasn’t changed in comparison to older versions, you don’t need to change anything.

• New It is now possible to adjust the max width of the main area, eg. in case you want to use the full page width for your content.

• New Images and Codefences are now respecting Hugo’s Markdown attributes.

• New The theme has updated its Mermaid dependency to 10.6.0. This adds support for block diagrams.

• New This release fixes a long outstanding bug where the page wasn’t repositioning correctly when going forward or backward in your browser history.

5.25.0 (2024-02-29)

• Change This release deprecates the attachments shortcode in favor of the new the resources shortcode.

  If you are using Hugo below 0.123.0, you don’t need to change anything as the old shortcode still works (but may generate warnings).

  Anyways, users are strongly advised to migrate as the attachments shortcode will not receive support anymore. Migration instructions are listed on the attachments shortcode page.

• Change If you run Hugo with GitInfo configured, the default page footer now prints out name, email address and date of the last commit. If you want to turn this off you either have to run Hugo without GitInfo (which is the default) or overwrite the content-footer.html partial.

5.24.0 (2024-02-28)

• 0.112.4 This release requires a newer Hugo version.

• Change The topbar button received a way to add text next to the icon. For this, the original title option was renamed to hint while the new title option is now displayed next to the icon.

• Change The frontmatter option menuTitle is now deprecated in favor for Hugo’s own linkTitle. You don’t need to change anything as the old menuTitle option is still supported.

• 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 syntaxhighlighting 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 If the theme can not resolve a link to a page or image, you can now generate warnings or errors during build by setting link.errorlevel or image.errorlevel to either warning or error in your hugo.toml respectively. By default this condition is silently ignored and the link is written as-is.

  Please note that a page link will generate false negatives if uglyURLs=true and it references an ordinary page before 0.123.0.

  Please note that an image link will generate false negatives if the file resides in your static directory.

• 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 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.

• New Support for Hugo’s built-in figure shortcode.

• New On taxonomy and term pages you can now use prev/next navigation as within the normal page structure.

• New In additiion to the existing menu width customization, it is now also possible to set the width of the menu flyout for small screen sizes with the --MENU-WIDTH-S CSS property.

• New Improvements for accessibility when tabbing through the page for images, links and tab handles.

• New The editURL config parameter is now overwritable in your pages frontmatter. In addition it received more versatility by letting you control where to put the file path into the URL. This is achieved by replacing the variable ${FilePath} in your URL by the pages file path. You don’t need to change anything in your existing configuration as the old way without the replacement variable still works.

• New The themes config and frontmatter options received a comprehensive documentation update. In addition the theme switched from config.toml to hugo.toml.

• New Restored compatibility with Hugo versions 0.121.0 or higher for the highlight shortcode. This does not change the minimum required Hugo version.

• New Restored compatibility with Hugo versions 0.123.0 or higher for theme specific output formats and handling of taxonomy and term titles. This does not change the minimum required Hugo version.

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

  hugo.

  toml yaml json

  [params]
    author = 'Hugo'

  params:
    author: Hugo

  {
     "params": {
        "author": "Hugo"
     }
  }

  to

  hugo.

  toml yaml json

  [params]
    [params.author]
      name = 'Hugo'

  params:
    author:
      name: Hugo

  {
     "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 independent 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 independent 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.html partial 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 syntaxhighlighting 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 syntaxhighlighting 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

  --OPENAPI-CODE-theme: obsidian;
  --PRINT-OPENAPI-CODE-theme: obsidian;

• 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 through 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 event themeVariantLoaded 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 as well 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 as well 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 documentation.

  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 compatibility 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 tag taxonomy 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?

  1. Hide tags above title: Overwrite content-header.html with an empty file.
  2. Show tags between title and content: Overwrite heading-post.html and add {{ partial "tags.html" . }} to it.
  3. 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.

• New Support for the great VSCode Front Matter extension which provides on-premise CMS capabilties to Hugo.

  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

  ​

  frontmatter.json

  {
    ...
    "frontMatter.extends": [
        "./vscode-frontmatter/snippets.en.json"
    ]
    ...
  }

• 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 depending 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:

  ​

  layouts/partials/custom-header.html

  <script src="{{"js/jquery.min.js"| relURL}}" defer></script>

• Change Mermaid diagrams can now be configured for pan and zoom on site-, page-level or individually for each graph.

  The default setting of on, in effect since 1.1.0, changed back to off as there was interference with scrolling on mobile and big pages.

• Change The theme is now capable to visually adapt to your OS’s light/dark mode setting.

  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.

• New GitHub 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 as well.

  To get rid of this undesired behavior you have two choices:

  1. 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.

     ​

     toml yaml json

     +++
     title = 'Showcase'
     
     [_build]
       list = 'never'
       publishResources = true
       render = 'always'
     +++

     ---
     _build:
       list: never
       publishResources: true
       render: always
     title: Showcase
     ---

     {
        "_build": {
           "list": "never",
           "publishResources": true,
           "render": "always"
        },
        "title": "Showcase"
     }

  2. 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). Don’t give this page a title as this will cause it to be shown in the breadcrumbs - a thing you most likely don’t want.

     ​

     toml yaml json

     +++
     [_build]
       list = 'never'
       publishResources = false
       render = 'never'
     +++

     ---
     _build:
       list: never
       publishResources: false
       render: never
     ---

     {
        "_build": {
           "list": "never",
           "publishResources": false,
           "render": "never"
        }
     }

     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.

     ​

     toml yaml json

     +++
     title = 'Credits'
     +++

     ---
     title: Credits
     ---

     {
        "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 unnecessary 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 compatibility.

• 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 theme now supports Hugo’s module system.

5.8.0 (2022-12-08)

• 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 highlighting 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 through 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 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=true and 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.

  Old	New
  <img src="pic.png?width=20vw&classes=shadow,border">	<img src="pic.png" style="width:20vw;" class="shadow border">

5.4.0 (2022-11-01)

• Change With 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 The math shortcode and mermaid shortcode now also support the align parameter if codefence syntax is used.

• 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).

• New Image 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:

  hugo.

  toml yaml json

  [outputFormats]
    [outputFormats.print]
      baseName = 'index'
      isHTML = true
      mediaType = 'text/html'
      name = 'print'
      path = '_print'
      permalinkable = false

  outputFormats:
    print:
      baseName: index
      isHTML: true
      mediaType: text/html
      name: print
      path: _print
      permalinkable: false

  {
     "outputFormats": {
        "print": {
           "baseName": "index",
           "isHTML": true,
           "mediaType": "text/html",
           "name": "print",
           "path": "_print",
           "permalinkable": false
        }
     }
  }

5.0.0 (2022-07-05)

• 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.

  <script defer src="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.

4.1.0 (2022-06-12)

• New While fixing issues with the search functionality for non Latin languages, you can now configure to have multiple languages on a single page.

4.0.0 (2022-06-05)

• 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.

  This applies to expand, include, notice and siteparam.

• 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.

3.1.0 (2022-03-15)

• New attachment and notice shortcodes have a new parameter to override the default icon. Allowed values are all Font Awesome 5 Free icons.

3.0.0 (2022-02-22)

• Breaking We made changes to the menu footer. If you have your menu-footer.html partial 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 Hugo’s 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.md	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 Hugo’s 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 Hugo’s 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:

  1. 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.

  2. 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 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 Hugo’s 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)

• Breaking Mermaid diagrams can now be panned and zoomed. This isn’t configurable yet.

• New Mermaid 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 0.121.0 of the Hugo binary for your OS (Windows, Linux, Mac).

Installation

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 the new command to create a new website:

hugo new site my-new-site

After that change into the directory:

cd my-new-site

Every upcoming command will be executed from inside your new site’s root.

Install the Theme

Downloading as Archive

You can download the theme as .zip archive and extract its content into them themes/hugo-theme-relearn directory.

Afterwards add this at the end of your hugo.toml.

theme = 'hugo-theme-relearn'

theme: hugo-theme-relearn

{
   "theme": "hugo-theme-relearn"
}

Using Hugo’s Module System

You can install the Relearn theme by following the standard documentation using Hugo’s module system:

hugo mod init example.com

Afterwards add this at the end of your hugo.toml.

[module]
  [[module.imports]]
    path = 'github.com/McShelby/hugo-theme-relearn'

module:
  imports:
  - path: github.com/McShelby/hugo-theme-relearn

{
   "module": {
      "imports": [
         {
            "path": "github.com/McShelby/hugo-theme-relearn"
         }
      ]
   }
}

Using Git Submodules

If you plan to store your project in a git repository you can create one with:

git init

Now add the theme as a submodule by:

git submodule add https://github.com/McShelby/hugo-theme-relearn.git themes/hugo-theme-relearn

Afterwards add this at the end of your hugo.toml.

theme = 'hugo-theme-relearn'

theme: hugo-theme-relearn

{
   "theme": "hugo-theme-relearn"
}

Create your Home Page

If you don’t create a home page, yet, the theme will generate a placeholder text with instructions on how to proceed.

Start your journey by creating a home page:

hugo new --kind home _index.md

The newly created home page content/_index.md is empty and you obviously should add some meaningful content.

Create your First Chapter Page

Chapters are meant to be top level pages that contain other child pages. They have a special layout style and often just contain the title and a brief abstract of the section.

Now create your first chapter page with the following command:

hugo new --kind chapter basics/_index.md

When opening the newly created file content/basics/_index.md, you should see the weight frontmatter with a number. This will be used to generate the subtitle of the chapter page, and should be set to a consecutive value starting at 1 for each chapter level.

Create your First Content Pages

Then create content pages inside the previously created chapter. Here are three ways to create content in the chapter:

hugo new basics/first-content/_index.md
hugo new basics/second-content/index.md
hugo new basics/third-content.md

Feel free to edit those files by adding some sample content and replacing the title value in the beginning of the files.

Testing your Website Locally

Launch your new web site by using the following command:

hugo serve

Go to http://localhost:1313 in your browser.

You should notice a few things:

1. The home page contains your provided text.
2. You have the menu Basics in the sidebar. Clicking on it reveals three submenus with names equal to the title properties in the previously created content pages.
3. While you are running hugo serve your page refreshes automatically when you change a content page. Neat!

Build and Deploy your Website

When your site is ready to be deployed, run the following command:

hugo

A public directory will be generated, containing all content and assets for your web site.

It now can be deployed to any web server by simply uploading its contents or you can check out one of Hugo’s many other deployment options.

Configuration

On top of Hugo’s global configuration options, the Relearn theme lets you define further options unique to the theme in your hugo.toml.

Note that some of these options are explained in detail in other sections of this documentation.

All config options

The values reflect the options active in this documentation. The defaults can be taken from the annotated example below.

Branding

The Relearn theme provides configuration options to change 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 through 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'

params:
  themeVariant: relearn-light

{
   "params": {
      "themeVariant": "relearn-light"
   }
}

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.

[params]
  themeVariant = ['relearn-light', 'relearn-dark']

params:
  themeVariant:
  - relearn-light
  - relearn-dark

{
   "params": {
      "themeVariant": [
         "relearn-light",
         "relearn-dark"
      ]
   }
}

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']

params:
  themeVariant:
  - auto
  - red

{
   "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']

params:
  themeVariantAuto:
  - learn
  - neon

{
   "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:

<link rel="icon" href="/images/favicon.bmp" type="image/bmp">

Change the Logo

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!

Syntax Highlighting

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 assets/css/chroma-<NAME>.css. To use it with your color variant you have to define --CODE-theme: <NAME> in the color variant stylesheet file.

For an example, take a look into theme-relearn-light.css and hugo.toml of the exampleSite.

Change the Variant (Advanced)

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 strings but 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.

[params]
  themeVariant = ['relearn-light', 'relearn-dark']

params:
  themeVariant:
  - relearn-light
  - relearn-dark

{
   "params": {
      "themeVariant": [
         "relearn-light",
         "relearn-dark"
      ]
   }
}

you now write it that way:

[params]
  [[params.themeVariant]]
    identifier = 'relearn-light'

  [[params.themeVariant]]
    identifier = 'relearn-dark'

params:
  themeVariant:
  - identifier: relearn-light
  - identifier: relearn-dark

{
   "params": {
      "themeVariant": [
         {
            "identifier": "relearn-light"
         },
         {
            "identifier": "relearn-dark"
         }
      ]
   }
}

The identifier option is mandatory and equivalent to the string in the first example. Further options can be configured, see the table below.

Modify Shipped Variants

In case you like a shipped variant but only want to tweak some aspects, you have two choices:

1. Copy and change

   You can copy the shipped variant file from the theme’s assets/css directory to the site’s assets/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 chosen name.

2. Create and import

   You can create a new variant file in the site’s assets/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 chosen name.

   For example, you want to use the relearn-light variant but want to change the syntax highlighting schema to the one used in the neon variant. For that, create a new assets/css/theme-my-branding.css in your site’s directory and add the following lines:

   ​

   assets/css/theme-my-branding.css

   @import "theme-relearn-light.css";
   
   :root {
     --CODE-theme: neon; /* name of the chroma stylesheet 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:

   hugo.

   toml yaml json

   [params]
     themeVariant = 'my-branding'

   params:
     themeVariant: my-branding

   {
      "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.
