Yeah CSS is now decent. The only problem is that the nesting is not very well supported yet. It’s something like only browsers > 2023 and let’s be realistic people run old machines.
We still see somewhat old browsers, especially from people using Safari on Apple devices (because IIRC it only updates when you update the whole OS). But it's a lot better than it used to be thanks to most browser having auto-updates
Definitely not widely supported enough. Made the switch from sass back to css quite a while ago and let postcss polyfill less supported features like nesting.
Yeah, I was reading about PostCSS the other day, but still too lazy to change my environment. To be fair I only need the nesting polyfill and some kind of minifier, the rest I can live with native stuff.
