This is in Eleventy, with the LaTeX math expressions embedded in Markdown.</p><p>While KaTeX includes the "output" option (<a href="https://katex.org/docs/options" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="">katex.org/docs/options</span><span class="invisible"></span></a>) to do HTML, MathML, or both (default: both), the plugin doesn't seem to expose that option, and since the MathJax one does just MathML, it looks right for me in NetNewsWire (macOS) and CapyReader (Android).</p><p>The post is here (<a href="https://reillyspitzfaden.com/posts/2025/06/reverb-part-1/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">reillyspitzfaden.com/posts/202</span><span class="invisible">5/06/reverb-part-1/</span></a>) and the feed is here (<a href="https://reillyspitzfaden.com/blog/feed.xml" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">reillyspitzfaden.com/blog/feed</span><span class="invisible">.xml</span></a>), and I'd be interested to hear if it's working for other people.</p><p><a href="https://hachyderm.io/tags/LaTeX" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>LaTeX</span></a> <a href="https://hachyderm.io/tags/KaTeX" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>KaTeX</span></a> <a href="https://hachyderm.io/tags/MathJax" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>MathJax</span></a> <a href="https://hachyderm.io/tags/Eleventy" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>Eleventy</span></a> <a href="https://hachyderm.io/tags/11ty" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>11ty</span></a></p>
