Grid Lanes: the Future of Masonry Layout

Go @rmondello.com go! It was 4+ years ago I first heard them talk about getting rid of passwords, and it’s so impressive how far Apple, and the whole industry, has come towards that goal! #Identiverse

Icon-only options in a customizable <select> break three things: ❌️ users who don't recognize the icon have no help ❌️screen readers have nothing to announce ❌️browsers w/o support show an empty dropdown There's just 1 fix for all three cases: keep the text Learn more:

The golden rule of Customizable Select

Customizable select is coming to Safari 27.

Customizable select is so powerful -- it's fully style-able with custom arrows, icons, color swatches, rich option layouts. But to make sure everyone can enjoy it, there’s one rule to follow: always include text in your options. We show you why this rule is so important: webkit.org/blog/18117/t...

The Safari team's reason for opposing Web MCP struck a cord with me. It is something I've struggled to articulate in the past. In fact, their comments contain the seed of a design principle that the W3C should adopt. cloudfour.com/thinks/impro...

Plus, the entire team is really passionate - they all lit up talking about so many things along the way. By the way @jensimmons.bsky.social, I've been reading the Safari release notes this past year and it's consistently amazed me how much is being shipped. Bravo to your team!

This group lab was really good. My takeaways: - they prioritize features based on use cases and the value it provides to users - web performance is an infinite game (never done) - the new <model> element is supported across Apple devices/browsers - spatial CSS is super exciting!

I thought customizable select would be the biggest news this year. But somehow seeing SVG getting some long missing love by a major browser feels even better. And of course the model tag hits close to home right now. Gonna be a lot of fun ahead.
