Modern CSS is indeed great. I'm using modern CSS, htmx, and Haskell to develop apps and am loving it.

I haven't touched Haskell in quite a while! If you ever feel like sharing any info about your experience working with it for web service dev, I'd be really interested to read it!

Same but with Swift instead of Haskell. I’m an iOS/macOS developer, but I have to do a web app currently, and I was pleasantly surprised by how powerful and relatively easy CSS is.
