@U0VQ4N5EE very similar to your question. did you find anything?

Worst case I’ll use string match/replace but it would be nice to load the css as data. even better would be css -> garden i.e. round-trip Garden css

I haven't finished it, but the suggestion to use ANTLR4 sounds promising https://github.com/antlr/grammars-v4/tree/master/scss

I've experimented a tiny bit with this http://cssparser.sourceforge.net/

See https://github.com/lambdaisland/ornament/blob/main/repl_sessions/cssparser.clj

looks pretty simple, thanks for the reference. I ended up just doing string replace with an xpath-like concept that did the job

Yeah, for css that might be good. My original problem was scss 😞

But, on the other hand, I resigned at that job, so don't have to fix the CSS anymore 😄
