Not counting at #w3cTPAC, the prior #CSSWG F2F meeting I went to was 2.5y ago, also in Cupertino, and before that 2019 in SF. Good to see so many longterm colleagues in-person.#W3C #CSS #webStandards^1 http... tantek.com

Merry Christmas 🎄 !
I am wondering are there folks in Browser teams who can elaborate of exposing the UI theme tokens of system and browser to the web app developers?

Consumer Semantic Theming in addition to custom/light/dark, providing the "native". But the amount of colors which passed down to CSS is far from sufficient. The browser as native application consumes OS theme and also has own customization ➡️ CSS

Looking for a lead.

Cheers in New 2026 🎠year!

✨When you put developers, standards, and sushi 🍣 in one room … magic happens! At #w3cTPAC in Kobe, 30+ folks turned an evening into a #hackathon: 17 projects in 90 minutes! From #CSS playgrounds to data dashboards, the results were useful and highly creative.

Hackathons like this one remind us that the web moves forward when people show up, try things, and share what they learn.

Thanks to @elena and all who made it happen! See you next time in #Dublin 🇮🇪!

At #w3cTPAC in Kobe 🇯🇵, several W3C chartered work groups as well as community-run groups had #AI on their group meeting's agenda. For example, #WebNN got fresh proposals (dynamic shapes, tensor binding), and WebMCP got more in-depth discussion as way to let web apps expose JavaScript-based tools to AI agents integrated in browsers.
