Our Commentary ​

I always appreciate these "What's !important" roundups from CSS-Tricks. They're fantastic for catching up on those smaller, but incredibly useful, web platform features that might otherwise slip under the radar. Light/dark favicons are a nice touch for user experience, and @mixin in native CSS is something I've been looking forward to. It's a good reminder that the web platform is constantly evolving, and even seemingly minor additions can significantly improve developer workflows and user interfaces.
