Many of his examples are great, but the <code>parent</code> selector instantly peaked my interest.</p> +<p>Being able to target an element’s parent always becomes a minor annoyance (since vanilla CSS does not support it) - so you always end up having to do something a little ugly like:</p> +<pre><code>var el = document.getElementById('custom-div'); +var parent = el.closest(selectors); +</code></pre> +<p>And then add any custom styling to the parent element directly in JavaScript - or toggle a class which opens a whole other can of worms.</p> +<h2 id="save-the-day-with-jsincss-parent-selector-and-qaffeine">Save the day with jsincss-parent-selector and qaffeine</h2> +<p>By using the <code>jsincss-parent-selector</code> and <code>qaffeine</code> plugins we can target an element’s parent in CSS without breaking a sweat. Let’s break it down:</p> +<h3 id="import-the-packages">Import the packages</h3> +<pre><code>npm install jsincss-parent-selector qaffeine +</code></pre> +<h3 id="html-ex.-index.html">HTML (ex. index.html)</h3> +<p>Now we add our very simple HTML skeleton:</p> +<pre><code><!doctype html> +<html> + <head> + <link rel="stylesheet" href="output.css"> + </head> + <body> + <header> + <main> + <h2>This is a header</h2> + </main> + </header> + </body> + <script src=output.js></script> +</html> +</code></pre> +<h3 id="javascript-ex.-input.js">JavaScript (ex. input.js)</h3> +<pre><code>const qaffeine = require('qaffeine') +const parent = require('jsincss-parent-selector') + +qaffeine( +{ + stylesheet: {}, + rules: { + parent + } +}, +'input.css', +'output.js', +'output.css' +) +</code></pre> +<h3 id="css-ex.-input.css">CSS (ex. input.css)</h3> +<pre><code>header { + display: block; +} +main[--js-parent] { + background: blue; +} +</code></pre> +<p>Then simply run <code>node</code> against your <code>js</code> file. That’s it! I would also suggest checking out Tommy’s video covering this topic if you prefer to follow along.</p> +<footer role="contentinfo"> + <h2>Menu Navigation</h2> + <ul id="menu"> + <li><a href="/">Home</a></li> + <li><a href="/projects">Projects</a></li> + <li><a href="/uses">Uses</a></li> + <li><a href="/wiki">Wiki</a></li> + <li><a href="/resume">Resume</a></li> + <li><a href="/colophon">Colophon</a></li> + <li><a href="/now">Now</a></li> + <li><a href="/donate">Donate</a></li> + <li><a href="/atom.xml">RSS</a></li> + <li><a href="#top">↑ Top of the page</a></li> + </ul> + <small> + Built with <a href="https://git.sr.ht/~bt/barf">barf</a>. <br> + Maintained with ♥ for the web. <br> + Proud supporter of <a href="https://usefathom.com/ref/DKHJVX">Fathom</a> & <a href="https://nextdns.io/?from=74d3p3h8">NextDNS</a>. <br> + The content for this site is <a href="https://creativecommons.org/licenses/by-sa/2.0/">CC-BY-SA</a>.<br> The <a href="https://git.sr.ht/~bt/bt.ht">code for this site</a> is <a href="https://git.sr.ht/~bt/bt.ht/tree/master/item/LICENSE">MIT</a>. + </small> +</footer>
