Learn how browsers are working together to make it easier to build for the web
summary
Browsers coordinate to shrink real interoperability gaps by prioritizing fixes and sharing tests and specs via Interop 2022 and Compat 2021. Example: gap in Flexbox: 2 years 6 months between Firefox (Oct 2018) and Safari (Apr 2021), blocking straightforward usage until Chrome shipped (July 2020) and Safari completed support. Engineering efforts include Web Platform Tests and a Grid NG rendering rewrite that lifts Chromium grid compatibility from 3% to 97%, with 15 focus areas tracked publicly.
