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>Save the day with <a href="https://www.npmjs.com/package/jsincss-parent-selector">jsincss-parent-selector</a> and <a href="https://github.com/tomhodgins/qaffeine">qaffeine</a></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>Import the packages</h3> +<pre><code>npm install jsincss-parent-selector qaffeine +</code></pre> +<h3>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>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>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!
