We got an experiment for preview in DevEdition that we hope makes cross-browser development easier.
The new Compatibility side-panel in Inspector shows which CSS declarations are unsupported in certain browser versions. It’s powered by MDN’s browser compatibility data.
Click each property to learn more on MDN and customize the supported browsers in settings.
We are especially interested in how correct and actionable the results are. Give it a try and let us know how it goes!
