Tailwind CSS Syntax

[AbeEstrada]

Is there a solution for this?
Does the LSP address this issue?

I think this issue is from your LSP, so what we need is the part of your language config which sets up your LSP for CSS.
Also take a look into the log what it's saying. You can execute add -vvv like hx -vvv . to get more into the logs.
