It's taking me forever, but I'm getting closer to a react-resizable-panels version 4 release. The major difference will be support for more size units (%, pixels, rem/em, vh/vw)

To Infinity… But Not Beyond!
More explorations of ways to abuse the CSS `infinity` keyword, this time with more than just lengths.

Container queries aren't about size anymore. Now we have style, scroll-state, anchored, and who knows what's coming? 🤩

The other day @davatron5000.bsky.social shared a link to the new `stretch` keyword in CSS – and I saw a lot of questions about how it's different from 100% (or 100vh when doing full-screen layouts). So I made a quick video to show how these all work! #CSS

:state() is a great mechanism for matching elements without having to tweak their DOM.
What if we could expand it to…
…regular elements? github.com/whatwg/html/...
…selectors (as an alias)?

This is also pretty rad, because in addition to being local state, it also registers your state as enums that you can use to STYLE your components with the ":state" CSS selector.

I really wish Disposables were inherited through closures. But that's not the case. You have to dispose of them manually if you wrap them in a function.
This will be solved with disposable stacks though.
