Solving Sticky Hover States with @media (hover: hover)

18.2.2020
Mezo Istvan does a good job of covering the problem and a solution to it in a blog post on Medium¹. If you tap on something that has a :hover state but you don't leave the page then, on a mobile device, there is a chance that :hover state "sticks." You'll see this with stuff like jump-links used...

Web Component for a Code Block

18.2.2020
We'll get to that, but first, a long-winded introduction. I'm still not in a confident place knowing a good time to use native web components. The templating isn't particularly robust, so that doesn't draw me in. There is no state management, and I like having standard ways of handling that. If...

Don’t segment the web.”“Hybrid apps don’t work as well as native apps.”“CSS preprocessors shouldn’t...

A clever idea from Tom Hicks combining MutationObserver (which can "observe" changes to elements like when their attributes, text, or children change) and the Web Audio API for creating sounds. Plop this code into the console on a page where you'd like to listen to essentially any DOM change...

“CSS4” Update

16.2.2020
Since I first chimed in on the CSS4¹ thing, there's been tons of more discussion on it. I'm going to round up my favorite thoughts from others here. There is an overwhelming amount of talk about this, so I'm going to distill it here down as far as I can, hopefully making it easier to follow. Jen...

The <details> and <summary> elements in HTML are useful for making content toggles for bits of text. By default, you see the <summary> element with a toggle triangle (▶︎) next to it. Click that to expand the rest of the text inside the <details> element. But...

While You Weren’t Looking, CSS Gradients Got Better

14.2.2020
One thing that caught my eye on the list of features for Lea Verou's conic-gradient() polyfill was the last item: Supports double position syntax (two positions for the same color stop, as a shortcut for two consecutive color stops with the same color) Surprisingly, I recently discovered most...
