<p>Let’s start with the most basic and perhaps most useful customization: modifying the <code><head</code>>.
|

This is useful for adding your own CSS and JavaScript files, changing certain metadata, or adding icons.</p>

</div>
|

<div class="paragraph">
|
||
<p>First, copy the <code>head</code> partial from the theme (<code>theme/contentful/layouts/partials/head.html</code>) to your own (<code>layouts/partials/head.html</code>).

We’re simply taking advantage of <a href="https://gohugo.io/templates/lookup-order/">Hugo’s lookup order</a> where we’ve override the <code>head</code> partial with our own copy.</p>

<div class="paragraph">
|

<p>In my case, I often use certain JavaScript libraries like <a href="https://www.mathjax.org/">MathJax</a> for mathematical typesetting, <a href="https://prismjs.com/">Prism</a> for syntax highlighting, and <a href="https://github.com/francoischalifour/medium-zoom/">medium-zoom</a> for interactive image zooms.</p>

<p>Since most of the JavaScript libraries used here are not really a requirement (except for MathJax for mathematical typesetting), I’ve set them to be loaded at the end of the page loading with <a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script"><code>defer</code> attribute</a>.
|
||
If you have an inline script, you can simply wrap it in an event listener for page loading (<code>window.addEventListener("load", your_function_goes_here)</code>).</p>
|
||
</div>
|
||
<div class="paragraph">
|
||
<p>If you want document-specific libraries, you have to pass some raw HTML through the parser of the document.
|
||
For Goldmark, the default Markdown parser starting <a href="https://gohugo.io/news/0.60.0-relnotes/">Hugo v0.60.0</a>, blocks raw HTML by default and you can disable it by setting <code>markup.goldmark.renderer.unsafe</code> to <code>true</code>.</p>
|
||
</div>
|
||
<div class="paragraph">
|
||
<p>For Blackfriday, it parses even the raw HTML just fine.
|
||
Though, you have to set it as the default Markdown parser.</p>
|

</div>
|
||
<div class="paragraph">
|
||
<p>For <a href="https://asciidoctor.org/">Asciidoctor</a>, you can use <a href="https://asciidoctor.org/docs/user-manual/#passthroughs">passthroughs</a> to get raw HTML through.</p>
