Build accessible components—framework or not—without the hand-waving. ♿✨

@sleeplessbyte.bsky.social shares practical patterns and fixes for interactive UI that actually ship. Less theory, more “here’s how.”

@beyondtellerrand.bsky.social since there are so.many D&D falls at #btconf I have to ask you the question where can I still get this D&D starter set as a present for a young boy (in German)? Seems to be out of stock everywhere 🙁

Liege ich richtig damit, dass die Arbeitgeber, welche Einschnitte von den GKV verlangen, dieselben sind, die laufend Mitarbeiter – und damit Beitragszahler – durch Outshoring, Roboter und KI ersetzen?

@therealnooshu.bsky.social Hey Matt, I read between the lines that you might be at perfnow and I kept my eyes peeled for you, but haven't been able to spot you. Is it correct that I will find you around the "Brits pack", being Andy, Harry and Ryan? Then I'll come by and say hi!

@marcysutton.com Great talk!! 👏🫶🚀

As we had the topic of skip links: would you support the idea of also putting in skip links into your page for skipping content blocks in reverse direction for folks that tabbed too far or wanted to peak behind a block and decide they wanna go back up? #perfnow

@tammyeverts.com weird that too fast does lead to lower conversion rates. #perfnow

There’s a new type of CSS scroll-state query coming: “scrolled”.

This one remembers the last direction you scrolled into, which you can use to build “hidey bars”: when scrolling down (or having scrolled down), the hidey bar hides itself. When then scrolling back up, the hidey bar reveals itself.

Stumbled upon this comment to the below article and I think they've nailed it.
Screenshot of a comment by user dsch, posted 22 hours ago. The comment reads: “Brain drain in this case is the mirror image of enshittification, applied on the inside of the service (employees) rather than the outside (users).”

Less than a month away - every #FFConf ticket comes with a free bucket of pure unadulterated inspiration, but caution: side effects of buzzing head have been known.

(Plus, prices switch to late bird in a few weeks - spread the word!)

2025.ffconf.org
The speakers for FFConf in a grid with topics: distributed power, inclusivity by design, design systems and web components, privacy and ethics, the good internet, ai brain drain, code and culture and finally: journey to coder.

Did a new one
Government style ad in watercolour. Image of a burglar stealing a painting from the wall of a home. Tagline: "It's not theft... if you say you're using it to train your AI algorithm". Body text: "Theft is now legal, so we can boost the economy by eliminating jobs. If that doesn't make any sense, ask a chatbot to explain it to you." HM government logo in the corner.

I've been mourning our loss of web events in AoNZ lately (rip Webstock, Gather, Codemania, KiwiFOO et al) and this gets at why. I'm so looking forward to @beyondtellerrand.com and @ffconf.org next month.

I often see the word 'kerning' used incorrectly by CSS heads when the term they're actually looking for to describe letter spacing is 'tracking'. Let me explain using CSS terminology!

Tracking is the same as gap in flex layouts; consistent spacing applied across the entire text.

But what if... 🧵
A graphic featuring repeated square shapes with consistent gaps between them. The text reads "Tracking/Letterspacing = Flex Gap. Consistent spacing applied across the entire text"

I dug into progressive image rendering and found a bunch of common assumptions aren't quite true.

➡️ JPEG & WebP progressive-renders worse in Safari
➡️ AVIF _does_ support progressive
➡️ But JPEG XL in Safari doesn't
➡️ JPEG XL decodes much slower than AVIF
⬇️ and more

@kevinpowell.co @henrihelvetica.bsky.social listened to your discussion / musings yesterday on meetups and conferences. I agree with your diagnosis! And would like to add that meetups also fail because people are not sitting in the office anymore which used to make swinging by at a meetup easy.

As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.

So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.
