What a fantastic two days at @perfnow.nl! Learned so much, not just from the talks, but from all the great people. Time to digest those notes 😅! It was a blast being the #magento dev in the crowd explaining @hyva.bsky.social to folks who hadn't heard of it yet 😁

Question for @tunetheweb.com for @perfnow.nl, can you detect if the 'prerender until script' is supported and fallback to prefetch if not yet supported

Enjoyed this writeup by @dbushell.com about the usability of custom cursors in #CSS
dbushell.com/2025/10/27/c...
When I visited the Wondermake website I was surprised the cursor was that big. I didn't realize it was responding to my OS settings. Neat. Interesting that Windows doesn't do the same.

Anchor positioning is not yet baseline, but you can use it in production with a polyfill - anchor-positioning.oddbird.dev (and in fact, we're using it on oddbird.dev).

So I noticed @fylgja.dev was without Schema data since the transition to @astro.build, so as of today that's back. Thanks to this I did have time to look into improving this even more 😁

It's always surprising how many sites use 
's for accordions. The most recent example I saw was the Tailwind Cheatsheet by Kombai (kombai.com/tailwind/che...), shared by @frontendfocus.bsky.social

I have been using the native git blame feature in #VSCode for over a month now, and I officially dropped the need for GitLens, since that is pretty much why I used it.
It's always nice to drop a heavy extension 😁

Great article on where `aria-label` should & shouldn't be used benmyers.dev/blog/dont-us...
Don’t Use aria-label on Static Text Elements
Don’t use the aria-label or aria-labelledby attributes on divs, spans, or other elements representing static/noninteractive text-level semantics, unless you’re also updating roles.
