My Google IO demo of HTML in Canvas and Web MCP github.com/PaulKinlan/3...

I really don't like to admit that, but agents are no longer bad at CSS. I'm playing around with these skills bundled by Googlers into the Modern Web Guidance, and they are impressive. Really good presentation @philipwalton.com 👏 developer.chrome.com/docs/modern-... #css

My talk on Modern Web Guidance is up! youtu.be/bo3i0FzDUYo This talk is a deep dive into how Modern Web Guidance works and why it's useful. 👉 Make sure you watch until the end, where I show some live demos that really highlight this tool's capabilities!

HTML might be getting out of order streaming natively in the future. I really like this: developer.chrome.com/blog/declara...

Here's the recording of this year's “What's new in Web UI” talk @una.im and I gave at Google I/O earlier this week. youtu.be/uT7MVcCQ4rw Very happy with how it went, and I think you might find it useful, so give it a watch 😊 #ChromeDevRel #GoogleIO

What's new in Web UI: 2026 Edition ✨ @bram.us and I go over 35+ new CSS, HTML, and JS features to help you build beautiful web experiences Video just went live: www.youtube.com/watch?v=uT7M...

Pretty excited about the Modern Web Guidance skills from Google. I had already created my own "semantic HTML" skill, but these are much better. https://developer.chrome...

✨ A challenge in today's web dev is telling AI agents to write modern code. Skills can help avoid legacy patterns and bloated JS. 🎉 We're teaming up with Chrome to bring you Modern Web Guidance: skills for web platform expertise, best practices, and modern API patterns!

We've been COOKING Modern Web Guidance is a skill pack that helps your coding agent write better, faster, more accessible and secure code Get it at goo.gle/mwg We'd love to know what you think!

@philipwalton.com to discuss it in more detail in 30 mins! io.google/2026/explore...

Thrilled this is out, keeping quiet has been SO HARD! 🤐 I’ve had the opportunity to contribute as a domain expert consultant over the past few months, and saw firsthand the level of thoughtfulness and care that went into it. Proud to have played a small part, and excited to see what folks build! ❤️

💥 Game changer for Web Development announced at GoogleIO- Modern Web Guidance! It’s expert-vetted skills for web development based on best practices of latest specs and APIs. It ensures your agent/coding harness doesn’t default to older and out of date patterns to build sites.

I'm going to be giving a talk that deep dives into Modern Web Guidance in 2 hours: bsky.app/profile/deve... You can find the talk details here: io.google/2026/explore...

🚨 What are some modern web platform (CSS, HTML, JS) features that you wish your AI agent utilized, but doesn't (or gets them wrong)? I’ll go first: - CSS: lh unit, trig functions, nesting - HTML: inert attribute - JS: Regex lookbehind, regex named groups, RegExp.escape(), Object.groupBy()

TypeScript excitement 😉 Congrats to @jakebailey.dev on updating upstream tsc to default to an unpinned *latest* yearly edition of ES20xx. Heading for TS 6.0 🎉 This mean less transpilation of new JS features & more use of native language features provided by JS engines 👍 github.com/microsoft/Ty...

You know that annoying experience on mobile websites where you need to find the little close button and can't swipe a menu closed? The solution is simpler than you think. With basic CSS scroll APIs, you can get built-in interruptible swipe gestures 🥳

The Chrome Identity and Payments team in Waterloo Canada is hiring several early/mid-career developers. I'm on the lookout for exceptional candidates with a passion for browsers and/or the identity/payments space! www.linkedin.com/posts/rick-b...

Being an old-school web dev is always like "Oh wait, I *can* use container queries now"

There are many goodies that are newly and widely available in Baseline. backdrop-filter is so much fun to work with and I am obsessed with AVIF images and the ability to animate from display: none with @starting-style. And how easy is it to lazy load images now? web.dev/articles/bas...

View Transitions are now in all browsers! They also landed in React! developer.chrome.com/blog/view-tr...

Chrome for Android can now help users adopt passkeys more seamlessly. If a user signs in with a saved password , your website can request that an associated password manager (in many cases on Chrome is Google Password Manager) creates a passkey automatically. developer.chrome.com/blog/automat...

A lot has happened since Chrome shipped Same-Document View Transitions in 2023. In 2024 we shipped Cross-Document VTs, added refinements such as `view-transition-class` and VT Types, and also welcomed Safari in adding VT support. And this year … well, I wrote a post summing it all up.

If we started Chrome Dev Summit again, would you be interested in it? (huh - apparently can't do polls here...), Please reply, Yes or No, or any other answer in between.

Scoped View Transitions are ready for testing in Chrome! SVTs expose el.startViewTransition() on HTML elements. The element creates a scope for the transition, ∴ the transition pseudo-elements are affected by ancestor clips and transforms. Multiple SVTs on separate elements can run *concurrently*.

🎉 Happy 30-month anniversary to Container Queries – in every browser since Feb, 2023. It was supposed to be impossible, but here we are! Why 2.5 years? Nothing will change tomorrow, but Baseline uses this milestone to signal confidence a feature has gained "wide" support. youtu.be/bhHV0rQ3-CQ

I know some people in the web community are concerned that Baseline will discourage devs from using new features—or anything not "Widely Available". Personally, I'm not worried about that at all. If anything, I think Baseline will speed up new feature adoption! Here's why 🧵

What new web features are your users actually ready for? Stop guessing. 🔮 Baseline helps you make data-driven decisions so you can ship the right features at the right time. Learn more and find your target with #WhatsMyBaseline → goo.gle/whats-my-baseline

Firefox shipping scheduler.postTask() and scheduler.yield() for all your long task-avoiding scheduling needs!!

Here's my talk from I/O along with the companion blog post that rounds up all of the links mentioned. It's been a very exciting year for the web, and all the new Baseline tooling we've just announced can help you understand when to adopt these new features. web.dev/blog/whats-n...

We've just published v5.0.0 of the web-vitals JavaScript library for measuring Core Web Vitals. github.com/GoogleChrome... As a major release, this includes a number of breaking changes as detailed in the upgrading doc: github.com/GoogleChrome... Please read carefully before upgrading. 1/5 🧵

So sad... One of the happiest things about building new CSS features was having Adam build cool stuff with them.

After 6 years of working closely alongside @nerdy.dev I am just rocked by this news. Still not ready to accept it TBH but I stand behind Adam as one of the most genuine, talented, effervescent devs I've ever worked with. If you're hiring snatch him up before I figure out a way to get him back 👀

Adam is the brightest, most authentic, inspiring, truly creative, high performing, deeply passionate, and nice person I have ever worked with. And then my employer decided to terminate his role. I am gutted and sick to my stomach. I will miss you, my friend 💔

It’s a sin that this happened to Adam. A true world class frontend engineer and a world class human. I remember being so excited when we first spoke about him joining Chrome and then talking VisBug. And he’s gone from strength to strength. What an epic own goal.

Someone hire this guy. He's one of the best. Hire him before someone else does.

Browser support info for CSS properties in VS Code is about to get a huge improvement Instead of looking at a list of browser versions and guessing if you can use a feature, now it'll just... tell you! Coming soon to the April 2025 stable release, or you can try it now in Insiders

My team is hiring! Come join us as a Developer Advocate at the intersection of Web, Chrome, ChromeOS and Android. The position is in Waterloo - Canada www.google.com/about/career...

We don't have an official CrUX Bluesky account, so for the moment I'll announce the monthly releases. And we're starting with a big one! 🆕 The 202501 release is now live on BigQuery! Check out the announcement post for the full info: groups.google.com/a/chromium.o... Highlights below 👇 🧵 1/10

We're shipping the new `Node#moveBefore()` API in Chrome 133! Read more in our latest blog post: developer.chrome.com/blog/movebef... Huge thx to @nomster.bsky.social for help bringing this to life, frameworks that helped test it, and the spec ecosystem for working with us to get it standardized!

For 12 Days of Web I answered a question that I've answered from stage in presentations but not written about: "Why not include polyfills in Baseline?" I also describe how Baseline can help you to decide what and when to polyfill 12daysofweb.dev/2024/how-to-...

Would you want core web vitals In Safari? Can you help me understand how you would use them and why numbers in one browser isn’t enough? (These may sound like silly questions, but I’d love to understand *your* specific context and use cases)

A post about how I try to meet the needs of a browser DevRel team that need to share information about new things, with those of developers who need to know what works now.

My analysis of the State of CSS and State of HTML 2024 surveys: https://patrickbrosset.com/articles/2024-11-08-state-of-css-and-state-of-html-2024/ Some very interesting take aways in there!

More people are using container queries than I realized! This is a great thread listing some of the sites using them in production, and also some graphs that show some clear positive trends 😄
