Delighted to have played a role in organizing one of the most exceptional collaborations ever! Go Edge and Go (sub)grid!!
🥳 Massive congratulations to the Edge team for working on this. The Edge team always impresses me with the attention to detail they bring to a project, and quality of implementation. wpt.fyi/results/css/css-grid…

This was a massive undertaking, a whole new tool to automate compat data collection, and thousands of PRs. I’m happy to have been on this journey with @queengooborg!

BOOOM!!! So excited!
The work done by open-ui.org/ is very exciting, and so important. Early experimentation work in Edge makes built-in fully-stylable and accessible <select>s possible, no libraries or custom JS needed. Check the demo in Edge Canary only: codepen.io/captainbrosset/pe…
