How do you do CI for mobile? Does it work well? I’m curious about the state of the art these days.

Dark mode. Do the websites & web apps made by your team support dark mode? If not, why not? What do you want to know most to help empower your team to support it?! What’s the blocker? What is confusing or hard about dark mode? #css #web #development #design

Do you make websites? What do you wish <select> listbox did? Or didn’t do? This is the HTML. Currently, it automatically creates a listbox with 4 options showing. <select id="foobar" multiple> If you want 6 items showing, you write <select id="foobar" multiple item="6">. What should it be?

Assuming the quality efforts that went into Safari 26.4, 26.5, 27.0 were some kind of one-and-done project? Nope! Just look at all the improvements in Safari Technology Preview 253. webkit.org/blog/18357/r...

I’ve been using Safari MCP a lot recently. It always just works. Today, I wasted my whole afternoon trying to get something to work with Chrome. Still doesn’t. What a PITA.

Previous default UA styling for Customizable select on the left. Current default UA styling in Safari 27.0. Thoughts? We just really wanted to give web developers a better starting place. 30 years of struggling to style form controls is enough.

Default look & feel of two drop-down menus, with and without groups of options. On the left, the original design from the CSS Working Group, in Chrome. On the left, what Safari 27.0 shipped, which is working it's way through the Working Group now.

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...

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.
