More holiday cheer. For those of you asking about Safari’s “stable” Interop 2025 score…

November's Baseline digest is here with big news for Next.js users → goo.gle/4q4jrXJ We're covering the framework's move to Baseline support, new case studies from Target and Cybozu, and a wave of widely available color features.

It took a while (mainly due to the huge quantity of data collected on some questions!), but the #StateOfHTML 2025 survey results are now live! 2025.stateofhtml.com/en-US/ Big thanks to @lea.verou.me who not only designed the original survey back in 2023, but then came back this year to update it.

🎉 And we're live! 🎉 We just launched CSS Wrapped 2025: our annual recap of all things CSS & web UI that landed in Chrome over the course of the year. 🚀 This is a big one! We highlighted 22 new features to help you build better on the web. Check out: chrome.dev/css-wrapped-2025

Might we all get a Chrome Dino in our stockings next Christmas? Apparently the people want it, it got 10k votes😄 (I totally want one) beta.ideas.lego.com/product-idea...

I’m often asked for freelance UI/UX designer recommendations, but my list is out of date — most folks I used to refer are now full-time or doing other work. Time to fix that. If you’re an independent UI/UX designer doing hands-on client work, drop your website/portfolio! DM/email fine too. [1/2]

Lots of people incorrectly claiming Chrome/Google "tried to kill JPEG XL". Just because an engine chooses not to be the FIRST to ship a new technology does NOT mean they are trying to kill it!

We've been working on a few proposals we'd like to bring to the web platform to make it easier to have more seamless navigations between pages. @nomster.bsky.social @foolip.org and @dbaron.org presented these at W3C TPAC annual meeting last week More details here: github.com/WICG/declara... 1/6 🧵

Out-of-order HTML patching, another proposal from TPAC, lets HTML be presented non-linearly, and a single file can update multiple parts of the page. Would this feature be useful to you?

streamHTMLUnsafe() was presented at TPAC last week. Finally, an API that lets you easily use the streaming HTML parser from JavaScript! Here's a quick overview:

My take on `oklch()` www.reddit.com/r/css/commen... In short, I use it to get around bugs, but I'm not a fan, I would not use it in gradients in general (makes them look dirty) and especially not in rainbow gradients in particular (makes yellows look poopy 💩 and I don't want 💩 in my 🌈) #CSS

🤩 There’s a very – VERY! – exciting animations/performance change available in Chrome Canary: Under the right conditions, `width`/`height` animations will no longer automatically force a Main Thread animation, but can be allowed to run on the Compositor.

not sure if non-Chinese speaking folks are able to generate translated captions for this but if you know me, you know that Chinese typography is one of my favourite things. this is a fascinating look into the MingKwai typewriter. youtu.be/yNoWMaOyWHY

Have you ever avoided using an a11y feature because of issues involved with IDREFs being global, or encountered bugs due to this? Please let us know! We have a meeting to discuss this next Wednesday (at TPAC) and would love to hear your stories, especially if they impacted users. cc @lea.verou.me

I'd consider myself an AI skeptic, but I find it strange when people bring up the copyright system as an anti-AI argument. Even if AI-created works did lead to the end of copyright, I'm not sure it'd be such a catastrophe. Recipes are not copyrightable, yet there are plenty of restaurants around.

The Web is the platform you are looking for. Pass it on.

Computing some preliminary analysis over the #StateOfHTML pain points data and some …interesting patterns are emerging 🙃

🤩 View Transitions excitement! Goooooo Ladybird! > This month, a lot of the underlying machinery for this has been implemented. It's going to take a bit longer before it's usable, but it's a good start to an exciting new web feature. buttondown.com/ladybird/arc...

🚀The new CSS sibling-index() and sibling-count() functions let us create staggered animations, dynamic color palettes, and even complex circular layouts with ease. I wrote about my first experiments with these fantastic new CSS additions. So much fun! ♥️ ✨ #CSS utilitybend.com/blog/styling...
