I’m trying to add custom classes to the
pre HTML tag using Markdown extra. After reading the fenced code block documentation, it looks like I have to set the
code_attr_on_pre variable on the markdown parser to
true. There are a few examples here. My 2 questions are
How do I set this variable to
true? I’ve tried a few different places in Grav’s own PHP files but haven’t gotten it to work. I don’t know PHP.
It looks like the behavior of adding classes to
codeis already enabled to some extent because if I enable markdown extra and type
var a = 2;
in markdown, the HTML output is:
<pre class=" language-js"> <code class=" language-js"> <span class="token keyword">var</span> a <span class="token operator">=</span> b<span class="token punctuation">;</span> </code> </pre>
Where was this behavior configured? Thanks!
