Seven different types of CSS attribute selectors

// This attribute exists on the element
[value]

// This attribute has a specific value of cool
[value='cool'] 

// This attribute value contains the word cool somewhere in it
[value*='cool']

<img data-src="unicorn.jpg" loading="lazy" alt=".." class="lazyload"/>

<script>
// Select all images with the class "lazyload"
const images = document.querySelectorAll("img.lazyload");
// Check if the browser supports the "loading" attribute
if ('loading' in HTMLImageElement.prototype) {
  // If so, we'll update all <img src> to point to the data-src instead
  images.forEach(img => {
    img.src = img.dataset.src;

Advanced SCSS

Or, 16 cool things you may not have known your stylesheets could do. I'd rather have kept it to a nice round number like 10, but they just kept coming. Sorry.

I've been using SCSS/SASS for most of my styling work since 2009, and I'm a huge fan of Compass (by the great @chriseppstein). It really helped many of us through the darkest cross-browser crap. Even though browsers are increasingly playing nice with CSS, another problem has become very topical: managing the complexity in stylesheets as our in-browser apps get larger and larger. SCSS is an indispensable tool for dealing with this.

This isn't an introduction to the language by a long shot; many things probably won't make sense unless you have some SCSS under your belt already. That said, if you're not yet comfy with the basics, check out the aweso
