Chapter 3


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.


The Attachments shortcode displays a list of files attached to a page


Nice buttons on your page


List the child pages of a page


Displays an expandable/collapsible section of text on your page


Displays content from other Markdown files
