Simplify your build toolchains with native Baseline support → goo.gle/46cTnCR Thanks to a collaboration between the Browserslist team and the WebDX Community Group, a new set of Baseline queries has been included directly in Browserslist itself.

🔥 New blog post! Covering, among other things: - Why making simple things easy and complex things possible is not enough - How to maximize your UI’s signal-to-noise ratio - Why you can’t uncover friction through user feedback - How to prioritize user needs lea.verou.me/blog/2025/us...

Did you know that AVIF (the AV1 Image File Format) was supported in all the major browsers (Firefox, Safari, Chrome/Edge)? This has been the case for almost 2 years at this point.

✅ Baseline now has full feature coverage, making it easier to know which web platform features are ready to use. Build the next wave of Baseline-powered tools and compete for $10,000 in prizes → goo.gle/424SBWc

There's a nice series from @sturobson.com getting into *why* and *how* to "un-Sass" CSS. www.alwaystwisted.com/articles/UnS... @jeffbridgforth.com is making a similar leap and shares how he's approaching it: css-tricks.com/is-it-time-t...

The WebDX Community Group is hosting an AMA on the r/webdev subreddit tomorrow. This is the group behind the "State of ..." surveys and Baseline, so if you have questions about those initiatives—or anything else around developer experience, join us! web.dev/blog/baselin...

Before, you needed a plugin to use Baseline semantics in your Browserslist queries. Now you don't! Just give it a target like `baseline widely available` and it'll work out of the box Available in [email protected] and later web.dev/blog/browser...

Neat! 📸

Summer rolls on, and so do the Baseline updates ☀️ In July, we saw JetBrains implement Baseline support, Chrome DevTools add Baseline data, and more VS Code-based IDEs inherit hovercards → goo.gle/40TcfUo

The State of CSS survey results are out. 🎉 2025.stateofcss.com/en-US/ Let me go over some details and see what surprises it includes. 🧵

just learned that CSS (as of "Baseline 2023") now supports nesting: caniuse.com/css-nesting I never managed to start using SCSS so I'm excited to be able to write things like this without a preprocessor: .cal-link { right: -18px; @media (max-width: 800px) { right: 0; } }

This is CSS performance problem I see all too often. The React website has some jank due due to their use of transition. Here is how to find what causes it and how and fix it

I've added Baseline status to the CSS property documentation tooltips I previously implemented in @chromium.social DevTools. #DX #DevEx #DeveloperExperience #UX #UserExperience #Baseline

If you wish to make a website from scratch, you must first invent the universe.

🚀 The #StateOfHTML 2025 survey is now open! ➡️ Take it now: survey.devographics.com/en-US/survey... 💡 Spending time to fill these out is an investment into your craft, as browsers are using the results to make prioritization decisions. You don't have to do it in one sitting (or even one device).

Ok hear me out. For today only.
