It’s interesting to me because CSS is very stable. It doesn’t really change that often. It’s great foundational knowledge to have for people who build for the web.

And nearly every step it's made has been for the better. I used sass on that blog, because a few corner case features weren't widely available when I last did work on the style, but for the last 3 projects I've worked on, I don't use it anymore. Pure css can do basically everything I needed before. Sure, I bundle using bun's bundler, but that's for performance optimization, nothing more
