New in Chrome DevTools: Instantly check CSS feature compatibility with Baseline! Chrome DevTools now displays the Baseline status for CSS properties right in the Elements panel - Baseline gives you clear info about which web features are ready to use today.

Handy! web.dev/blog/baselin...

Phil has a great set of posts on using Baseline!

Long text ➡️ short summary. The Summarizer API is available in Chrome Stable. In Chrome, you can use this API to condense long articles, transcripts, and more, with Gemini Nano. Which of Chrome's built-in AI APIs will you hatch? → goo.gle/3GltpD3

scroll-target-group is coming to Chrome 140 (stable next month)! Building on CSS carousel APIs, scroll-target-group lets you "enhance" elements into scroll markers, enabling you to build this scroll-spy effect in 2 lines of CSS! Makes for a great progressive enhancement! una.im/scroll-targe...

Got the chance to chat with Google's Kenji Baheux who has been working on Web AI APIs today! (I'm personally excited about the possibility of using on-device LLMs to screen interactions for toxicity.) Learn all about these news APIs: developer.chrome.com/docs/ai

@andreban.bsky.social and I are really proud of this one.

This is very useful and rewarding (even on a Friday night!) 🤩

Embedding third-party web content into your app (e.g. via iframes) can sometimes degrade the user experience. If this sounds familiar, we'd love your feedback on a new proposal to control the perf of embedded iframes or webviews:

Simeon and Oliver chat about what happened in the February 13, 2025 meeting of the WebExtensions Community Group. That may sound boring, but it was actually quite nice and fun, thankyouverymuch. backgroundcontext.com/episode/2025...

I just read Trump thinks Palestinians should just pack up and move to Jordan or Egypt since their cities are destroyed and maybe someday rebuild and return. He’s so casual about it as if these folks own second homes elsewhere. They’re not leaving their homeland.

Introducing "Copy console" in Chrome DevTools: one-click copy all console messages. Useful for pasting into LLMs / AI Code Editors for better fixes.

I have two new articles up on LLM streaming: 🧠 First, how even do LLMs stream responses: developer.chrome.com/docs/ai/stre.... 🎨 Second, best practices to render streamed LLM responses: developer.chrome.com/docs/ai/rend.... #WebAI #LLM #AI

New in Chrome 133 – which goes stable on Feb 4 – is a new method to move an element around the DOM. Unlike the classic way of removing+reinserting a node, this moveBefore method preserves the element’s state! Iframes remain loaded, animations don’t restart, … DEMO: codepen.io/bramus/full/...

🎉 OMG OMG OMG Chrome is shipping CSS attr() for every property!!! 🎉 I’ve been asking for this for over a decade!! w00t!!! 🤩 developer.chrome.com/blog/advance...

Chrome 133 goes beta today, with some very nice CSS/UI features: * Advanced `attr()` function * `:open` pseudo * Scroll State Container Queries * `text-box`, `text-box-trim`, and `text-box-edge` * popover=hint * Animation.overallProgress * DOM state-preserving move

Great series of posts by @christianliebel.com on web.dev, covering the capabilities and limitations of LLMs running in the browser, and a walkthrough on building an on-device chatbot. #WebAI #PromptAPI #WebLLM #GenAI
