Many of his examples are great, but the `parent` selector instantly peaked my interest. - -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: - - - var el = document.getElementById('custom-div'); - var parent = el.closest(selectors); - - -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. - -## 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> - -By using the `jsincss-parent-selector` and `qaffeine` plugins we can target an element's parent in CSS without breaking a sweat. Let's break it down: - -### Import the packages - - - npm install jsincss-parent-selector qaffeine - - -### HTML (ex. index.html) - -Now we add our very simple HTML skeleton: - - - <!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> - - -### JavaScript (ex. input.js) - - - const qaffeine = require('qaffeine') - const parent = require('jsincss-parent-selector') - - qaffeine( - { - stylesheet: {}, - rules: { - parent - } - }, - 'input.css', - 'output.js', - 'output.css' - ) - - -### CSS (ex. input.css) - - - header { - display: block; - } - main[--js-parent] { - background: blue; - } - - -Then simply run `node` against your `js` file.
