Sometimes it’s good to know when a browser feature is supported or not so you can do something. Perhaps load a polyfill or just choose a slightly different approach. This post looks at newish features in browsers and shows the test.

I’m such a :has() selector fanboy in CSS. We’ve covered it many times. But Bruce Lawson goes as far as to call it “The God Selector” because: [It] is omnipotent because it doesn’t require any structural relationship between the thing being checked and the thing being styled. In other words, you can select any element […]

A very nice one page website from the Brooklyn-based studio Selman showcasing just how much web (and other) technology was rooted in innovation by women. Printable posters, too.

Especially on mobile, the slide-out drawer UI/UX seems like a perfect fit for a popover, and works fine on desktop too.

Good observation in Bytes: … new CSS-in-JS libraries are popping up like it’s 2017 all over again. Panda came out last summer, Meta open-sourced StyleX in December, Material UI released PigmentCSS last month, and Restyle just launched a few weeks ago. It’s likely that server-side rendering screwed up the original “batch” of these tools. That, and, ya know, just using CSS is […]

I’m a big fan of View Transitions. Part of what they can do, animating elements across fresh page loads, is a uniquely powerful ability. The performance story, though, is a bit complicated. You might think because you don’t have to reach for a JavaScript framework with Single Page App abilities to do this, it could […]

Michelle Barker’s technique for popover footnotes is great. Here we look at ways we could fight the content duplication. There are ups and downs.

What happens with a CSS @keyframe animation like this when called? There is only one “keyframe” there at 50%. So what happens at 0% through the animation? The scale property is… whatever it already was. And at 100%? Back to whatever it already was. Assuming the default scale of 1, it will grow the element […]

Shape morphing animations can be awfully cool. They can be artistic and elaborate like the waving cape of a brand character, or simple and understated like video player controls morphing from one state to another. Alexandru-Gabriel Ică digs into doing this in <svg>. There is a fairly big prerequisite to these kind of animations: the […]

Boris Schapira takes a look at the Speculation Rules API that we just had a poke at around here. Boris notes that this idea of prefetching (or prerendering) the next page that a user might visit has quite a history. One of the players in this game, which is still a pretty good choice as […]
