We're excited to announce Interop 2026 → https://t.co/RPEpbTMQAf

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.

[Kadir Topal @atopal]

@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 https://t.co/TYlXEAqsY6 is also showing the Baseline status of a feature.

[Chrome for Developers @ChromiumDev]

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 → https://t.co/0aQBJu7Zc6

🙏🏼 Big thanks to @SachaGreif @DmitrySharabin @atopal @foolip

Nice talk about the new term Baseline, to check the status of web features https://t.co/ncTRsURgBU

I LOVE this …Chart of Shame on https://t.co/k0M1z1CgK4 “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!

@slicknet @bramus Not CSS specifically, but there is also https://t.co/XdEYvZUzKg that uses the web-feautures data.

[Rick Byers @RickByers]

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!

[Kadir Topal @atopal]

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: https://t.co/c1vIG6KWOF

@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.

[Kadir Topal @atopal]

@Paul_Kinlan @LeaVerou @stubbornella We do publicize a large part of our devsat surveys in WebDX: https://t.co/raeTbbHDyr

Snowballing is inevitable to a certain extent, but this is not convenience sampled, and you can see the breakdown in the appendix.

[Kadir Topal @atopal]

@EisenbergEffect @bramus @chriscoyier Good news! We now have that here: https://t.co/vPPbFgXD09 Let us know how it works for you :)

[Kadir Topal @atopal]

@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: https://t.co/09fN7TJn5j

[Kadir Topal @atopal]

@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 https://t.co/AR0dPLUKUG

[André Bandarra @andreban]

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

[Kadir Topal @atopal]

@andreban For me that would be size container queries, so incredibly useful: https://t.co/SB2c8owpJj
