<p>Mathematical notation in a Hugo project can be enabled by using third party JavaScript libraries.</p>
<p>In this example we will be using <a href=https://katex.org/>KaTeX</a>.</p>
<ul>
<li>Create a partial under <code>/layouts/partials/math.html</code></li>
<li>Within this partial reference the <a href=https://katex.org/docs/autorender.html>Auto-render Extension</a> or host these scripts locally.</li>
<li>Include the partial in your templates like so:</li>
</ul>
<div class=highlight><pre tabindex=0 class=chroma><code class=language-bash data-lang=bash><span class=o>{{</span> <span class=k>if</span> or .Params.math .Site.Params.math <span class=o>}}</span>
<span class=o>{{</span> partial <span class=s2>&#34;math.html&#34;</span> . <span class=o>}}</span>
<span class=o>{{</span> end <span class=o>}}</span>
</code></pre></div><ul>
<li>To enable KaTex globally set the parameter <code>math</code> to <code>true</code> in a project&rsquo;s configuration</li>
<li>To enable KaTex on a per page basis include the parameter <code>math: true</code> in content files</li>
</ul>
