We're excited to announce Interop 2026 → goo.gle/4tujOxz This year's cross-browser effort focuses on many developer-favorite features like CSS anchor positioning, scroll-driven animations, and view transitions to make the web more consistent for everyone.
@cos4ni2s @CSSWeekly It's complimentary, really. Caniuse has all the nitty gritty details, Baseline is meant to be a simplified indicator. Essentially answering the question: Is it implemented in all major browsers? That's why caniuse.com is also showing the Baseline status of a feature.
That “// TODO: build a tool for this” comment in your code could become an entry in the Baseline Tooling Hackathon. 👀 Submit a project that integrates Baseline with developer tools for a chance at $10,000 in cash prizes → baseline.devpost.com #WhatsMyBaseline
Gecko: Intent to Ship: CSS View Transitions L1 bit.ly/45Qt7g5
🚀 Blog post with more #StateOfHTML2025 background: lea.verou.me/blog/2025/stat… 🙏🏼 Big thanks to @SachaGreif @DmitrySharabin @atopal @foolip
Nice talk about the new term Baseline, to check the status of web features youtube.com/watch?v=QzfwNF…
I LOVE this …Chart of Shame on webstatus.dev/stats “Features missing in only one browser” 😍. Even lets you click on individual data points and see which features each browser is holding the Web back from. Hopefully it will motivate implementations of these features!
Opportunities vs. Problems Learn more about discovery: buff.ly/rQCOn66 How do you make sure you aren't stuck in problem-solving mode and remember to also look for unmet desires? Share your best tip in the comments below. #ContinuousDiscoveryHabits #prodmgmt #ux #engineering
@slicknet @bramus Not CSS specifically, but there is also webstatus.dev that uses the web-feautures data.
We're so used to what a "hard navigation" is supposed to look like, it's hard to believe that it doesn't actually have to look or feel any different from a soft nav. This is a huge upgrade to the architecture of the web platform!
150 proposals have been submitted for Interop 2025, and the call is officially closed. Now we need your help to add developer signals for those proposals. Please add your use cases and any additional data we should consider in the selection process: github.com/web-platform-t…
@Paul_Kinlan @LeaVerou @stubbornella I don’t recall the specific survey here, but if we can find it, we should be able to make public the relevant parts.
@Paul_Kinlan @LeaVerou @stubbornella We do publicize a large part of our devsat surveys in WebDX: github.com/web-platform-d… Snowballing is inevitable to a certain extent, but this is not convenience sampled, and you can see the breakdown in the appendix.
@EisenbergEffect @bramus @chriscoyier Good news! We now have that here: github.com/web-platform-d… Let us know how it works for you :)
@codepo8 Currently the feature set is limited, but eventually we should have the complete platform mapped. If there is anything you need, let us know please: github.com/GoogleChrome/w…
@codepo8 Hopefully we can establish the dashboard as a useful utility for those who work on the platform and those who write about it, that's the use case. It's based on the Web Features project that also powers the Baseline widget that's now on MDN and caniuse web.dev/blog/web-platf…
Safari 17.5 is out today! With • text-wrap: balance • light-dark() • @starting-style • @import <url> supports(<feature>); • AV1 for WebCodecs • WebGL EXT_conservative_depth and NV_shader_noperspective_interpolation And more! webkit.org/blog/15383/web…
What’s making headlines from #GoogleIO? We’re covering everything from Gemini Nano in Chrome to Baseline tooling and View Transitions API. Find out the latest in #AI advancements for developers now and follow along for more updates. goo.gle/3UKkrCi
So many nice features landed in Baseline in 2023! It's hard to choose, but I think my preferred one is Offscreen Canvas. What's yours? #Baseline #Compatibility
🚀Baseline has launched on caniuse.com! 🎉 You can now tell quickly whether a Web platform feature is Baseline 2023, “newly available”, or “widely available”. Learn more about the launch and Baseline 2023 features at goo.gle/baseline2023 #Baseline #Compatibility
@andreban For me that would be size container queries, so incredibly useful: developer.mozilla.org/en-US/docs/Web…
