Perfectly Pointed Tooltips: All Four Sides
Tooltips are a natural fit for the abilities of Anchor Positioning, which can help place them on *any* side or corner. It does make dealing with the pointer extra tricky though.

Responsive typography is getting so much simpler. This already works in a couple browsers, and the fallback is minimal:
--progress: progress(100vi, 320px, 1200px);
font-size: calc-mix(var(--progress), 1rem, 1.25rem);
But that will get even better…

They're such an exciting new part of the web platform, and I'm elated to see new and boundary-pushing effects making their way into production.

Tip: if you want an issue solved without doing the work yourself, don't use an accusatory tone when reporting it. And don't continue to do so when a response is provided pointing you in the direction to solve it.
