Inline code

Wrap inline snippets of code with <code>. Be sure to escape HTML angle brackets.

{% example html %} For example, <section> should be wrapped as inline. {% endexample %}

Code blocks

Use <pre>s for multiple lines of code. Once again, be sure to escape any angle brackets in the code for proper rendering. You may optionally add the .pre-scrollable class, which will set a max-height of 350px and provide a y-axis scrollbar.

{% example html %}

<p>Sample text here...</p>
<p>And another line of sample text here...</p>

{% endexample %}

Variables

For indicating variables use the <var> tag.

{% example html %} y = mx + b {% endexample %}

User input

Use the <kbd> to indicate input that is typically entered via keyboard.

{% example html %} To switch directories, type cd followed by the name of the directory.
To edit settings, press ctrl + , {% endexample %}

Sample output

For indicating sample output from a program use the <samp> tag.

{% example html %} This text is meant to be treated as sample output from a computer program. {% endexample %}
