  5. <p>I use <code>&lt;details&gt;</code>. I use <code>&lt;details&gt;</code> a lot. It is one of my favorite HTML elements.</p><p>Over time I’ve collected a bunch of add-on utilities to enhance <code>&lt;details&gt;</code> with new features and functionality. They’ve been super useful in <em>a bunch</em> of long-standing production implementations at Netlify:</p><p>I’ve decided to finally package those <code>&lt;details&gt;</code> helpers up and formally release them as a web component!</p><h2 id="lessdetails-utilsgreater" tabindex="-1"><code>&lt;details-utils&gt;</code> <a class="direct-link" href="#lessdetails-utilsgreater" aria-hidden="true">#</a></h2><pre class="language-html"><code class="language-html"><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>details-utils</span><span class="token punctuation">&gt;</span></span><br>  <span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>details</span><span class="token punctuation">&gt;</span></span>…<span class="token tag"><span class="token tag"><span class="token punctuation">&lt;/</span>details</span><span class="token punctuation">&gt;</span></span><br>  <br><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;/</span>details-utils</span><span class="token punctuation">&gt;</span></span></code></pre><p>At time of writing, this web component adds five new responsive-friendly enhancements to one or more <code>&lt;details&gt;</code> elements nestled inside:</p><ul><li>Force open/closed</li><li>Click outside to close</li><li>Close on <code>esc</code></li><li>Animate open/closed</li><li>Toggle root element <code>class</code></li></ul>

The optional <code>force-restore</code> attribute will restore previous state when the <code>force-open</code> or <code>force-close</code> media queries do not match.</p><p>The media query is optional, and using it as a bare attribute allows control of the state pre and post JavaScript.</p><pre class="language-html"><code class="language-html"><br><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>details-utils</span> <span class="token attr-name">force-open</span><span class="token punctuation">&gt;</span></span><br>  <span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>details</span><span class="token punctuation">&gt;</span></span>…<span class="token tag"><span class="token tag"><span class="token punctuation">&lt;/</span>details</span><span class="token punctuation">&gt;</span></span><br><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;/</span>details-utils</span><span class="token punctuation">&gt;</span></span><br><br><br><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>details-utils</span> <span class="token attr-name">force-close</span><span class="token punctuation">&gt;</span></span><br>  <span class="token tag"><span class="token tag"><span class="token punctuation">&lt;</span>details</span> <span class="token attr-name">open</span><span class="token punctuation">&gt;</span></span>…<span class="token tag"><span class="token tag"><span class="token punctuation">&lt;/</span>details</span><span class="token punctuation">&gt;</span></span><br><span class="token tag"><span class="token tag"><span class="token punctuation">&lt;/</span>details-utils</span><span class="token punctuation">&gt;</span></span></code></pre>

In my humble opinion, the super long list of things I’ve built using this is proof of that. I hope you can get some useful mileage out of them too!</p>
