One of my goals this year is getting better at CSS. I joke that my CSS skills peaked in 2015. But CSS has gained a ton of new, really cool things and browser support has been moving quickly compared the days of old.
This talk by Dylan Beattie from NDC London 2026 is a great introduction to what CSS is capable of these days.
I’m also slowly working through a course called CSS for JavaScript Developers by Josh Comeau, which is fantastically done.
