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).

If you're curious about anchor positioning, now is a great time to learn, and my email course will help you dive deep!

Remember that accessibility benefits everyone, including your future self. It is the ethical way to approach designing and building digital products that are truest to the inherent inclusive nature of the Web.

Thank you for coming to my short and sweet TED talk. 🥰

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.
