As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most.
So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion.

This is especially sad when I strongly believe plain HTML & CSS to be the most portable, robust and powerful way to author documents in 2025
Links get an <a>, but links that have a background colour on them are instead <div>s with a role... They have an href, which I guess they're using JS to, well, make it work like a link?🤦
And if you're going to use JS for that, you might as well offload hover/focus states there too 😭
