This page is a shameful copy of the great [Grav original page](http://learn.getgrav.org/content/markdown).
Only difference is information about image customization ([resizing]({{<relref"#resizing-image">}}), [add CSS classes]({{< relref "#add-css-classes" >}})...)

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 XHTML 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.
Grav ships with built-in support for [Markdown](http://daringfireball.net/projects/markdown/) and [Markdown Extra](https://michelf.ca/projects/php-markdown/extra/). You must enable **Markdown Extra** in your `system.yaml` configuration file
Without further delay, let us go over the main elements of Markdown and what the resulting HTML looks like:
The HTML `<hr>` element is for creating a "thematic break" between paragraph-level elements. In markdown, you can create a `<hr>` with any of the following:
*`___`: three consecutive underscores
*`---`: three consecutive dashes
*`***`: three consecutive asterisks
renders to:
___
## Body Copy
Body copy written as normal, plain text will be wrapped with `<p></p>` tags in the rendered HTML.
So this body copy:
```markdown
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.
<p>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.</p>
For quoting blocks of content from another source within your document.
Add `>` before any text you want to quote.
```markdown
> **Fusion Drive** combines a hard drive with a flash storage (solid-state drive) and presents it as a single logical volume with the space of both drives combined.
```
Renders to:
> **Fusion Drive** combines a hard drive with a flash storage (solid-state drive) and presents it as a single logical volume with the space of both drives combined.
and this HTML:
```html
<blockquote>
<p><strong>Fusion Drive</strong> combines a hard drive with a flash storage (solid-state drive) and presents it as a single logical volume with the space of both drives combined.</p>
> Donec massa lacus, ultricies a ullamcorper in, fermentum sed augue. Nunc augue augue, aliquam non hendrerit ac, commodo vel nisi.
>
> > Sed adipiscing elit vitae augue consectetur a gravida nunc vehicula. Donec auctor odio non est accumsan facilisis. Aliquam id turpis in dolor tincidunt mollis ac eu diam.
>
> Mauris sit amet ligula egestas, feugiat metus tincidunt, luctus libero. Donec congue finibus tempor. Vestibulum aliquet sollicitudin erat, ut aliquet purus posuere luctus.
> Donec massa lacus, ultricies a ullamcorper in, fermentum sed augue. Nunc augue augue, aliquam non hendrerit ac, commodo vel nisi.

The old mechanism for notices overriding the block quote syntax (`>>>`) has been deprecated. Notices are now handled via a dedicated plugin called [Markdown Notices](https://github.com/getgrav/grav-plugin-markdown-notices)
GFM, or "GitHub Flavored Markdown" also supports syntax highlighting. To activate it, simply add the file extension of the language you want to use directly after the first code "fence", ` ```js `, and syntax highlighting will automatically be applied in the rendered HTML.
Tables are created 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.
Add a HTTP `featherlight` parameter to the link image to disable lightbox. By default lightbox is enabled using the featherlight.js plugin. You can disable this by defining `featherlight` to `false`.
