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:
|
|
|
|
1. Markdown is simple to learn, with minimal extra characters so it's also quicker to write content.
|
|
2. Less chance of errors when writing in Markdown.
|
|
3. Produces valid HTML output.
|
|
4. Keeps the content and the visual display separate, so you cannot mess up the look of your site.
|
|
5. Write in any text editor or Markdown application you like.
|
|
6. 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.

## Paragraphs
|
|
|
|
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.
|
|
|
|
````md
|
|
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.
|
|
|
|
````md
|
|
# h1 Heading
|
|
|
|
## h2 Heading
|
|
|
|
### h3 Heading
|
|
|
|
#### h4 Heading
|
|
|
|
##### h5 Heading
|
|
|
|
###### h6 Heading

|

#### h4 Heading
|
|
|
|
##### h5 Heading
|
|
|
|
###### h6 Heading
|
|
{{% /notice %}}
|
|
|
|
## Horizontal Rules
|
|
|
|
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 `---`.
|
|
|
|
````md
|
|
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.

## Blockquotes
|
|
|
|
### Quotations
|
|
|
|
For quoting blocks of content from another source within your document add `>` before any text you want to quote.
|
|
|
|
Blockquotes can also be nested.
|
|
|
|
````md
|
|
> Donec massa lacus, ultricies a ullamcorper in, fermentum sed augue. Nunc augue, aliquam non hendrerit ac, commodo vel nisi.
|
|
>
|

|
|
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.

### Subscript and Superscript
|
|
|
|
You can also use subscript and superscript text. For more complex stuff, you can use the [`math` shortcode](shortcodes/math).
|
|
|
|
{{% badge color="fuchsia" icon="fa-fw fab fa-hackerrank" %}}Hugo{{% /badge %}} Since Hugo 0.126.0, you can [activate this through the _Hugo Extra Extension_](https://github.com/gohugoio/hugo-goldmark-extensions?tab=readme-ov-file#extras-extension) in your `hugo.toml`

## 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.
|
|
|
|

Markdown will automatically number each of your items consecutively. This means, the order number you are providing is irrelevant.

### Definitions
|
|
|
|
{{% badge color="#888cc4" icon="fa-fw fab fa-php" %}}PHP{{% /badge %}} 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
|
|
|
|

## Code
|
|
|
|
### Inline Code
|
|
|
|
Inline snippets of code can be wrapped with backticks `` ` ``.
|
|
|
|
````md
|
|
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.
|
|
|
|
````md

|
|
|
|
### 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.
|
|
|
|
{{% badge color="darkgray" icon="fa-fw fab fa-github" %}}GFM{{% /badge %}} 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.
|
|
|
|
See [Code Highlighting](shortcodes/highlight) for additional documentation.

## Tables
|
|
|
|
{{% badge color="darkgray" icon="fa-fw fab fa-github" %}}GFM{{% /badge %}} 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
|
|
|
|
{{% badge color="darkgray" icon="fa-fw fab fa-github" %}}GFM{{% /badge %}} Absolute URLs will automatically be converted into a link.
|
|
|
|
````md
|
|
This is a link to https://example.com.
|
|
````
|
|
|
|
{{% notice style="code" icon="eye" title="Result" %}}
|
|
This is a link to https://example.com.
|
|
{{% /notice %}}
|
|
|
|
|
|
### Basic Link
|
|
|
|
You can explicitly define links in case you want to use non-absolute URLs or want to give different text.
|
|
|
|
````md
|
|
[Assemble](http://assemble.io)
|
|
````
|
|
|
|
{{% notice style="code" icon="eye" title="Result" %}}
|
|
[Assemble](http://assemble.io)
|
|
{{% /notice %}}
|
|
|
|
### Link with Tooltip
|
|
|
|
For even further information, you can add an additional text, displayed in a tooltip on hovering over the link.
|
|
|
|
````md
|
|
[Upstage](https://github.com/upstage/ "Visit Upstage!")
|
|
````
|
|
|
|

|
|

|
|
{{% /notice %}}
|
|
|
|
### Link References
|
|
|
|
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.
|
|
|
|
````md
|
|
[Example][somelinkID]
|
|
|
|
[somelinkID]: https://example.com "Go to example domain"
|
|
````
|
|
|
|
{{% notice style="code" icon="eye" title="Result" %}}
|
|
[Example][somelinkID]
|
|
|
|
[somelinkID]: https://example.com "Go to example domain"
|
|
{{% /notice %}}
|
|
|
|
### Footnotes
|
|
|
|
{{% badge color="#888cc4" icon="fa-fw fab fa-php" %}}PHP{{% /badge %}} 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.
|
|
|
|
````md
|
|
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
|
|
|
|
### Basic Images
|
|
|
|
Images have a similar syntax to links but include a preceding exclamation mark.

### Image Effects
|
|
|
|
{{% badge color="#7dc903" icon="fa-fw fas fa-puzzle-piece" %}}Relearn{{% /badge %}} This theme allows additional non-standard formatting by setting query parameter at the end of the image URL. See the [image effects docs](authoring/imageeffects) for a detailed example and how to configure it.
|
|
|
|
#### Resizing
|
|
|
|
Add query parameter `width` and/or `height` to the link image to resize the image. Values are CSS values (default is `auto`).
|
