Stupid question about CSS changes

I’m a bit stuck on how I’d configure my project so that changes I do to the CSS come through in my `zola serve` dev environment. I’m using the Linkita theme. Just to test I set color:red to .font-bold, but it doesn’t do anything… I’m only used to webpack/vite development, so I’m a bit stuck on what steps to take here…

Hello, yet again, asking about it in the forum seems to help me find the answer myself.
So what you do is to cd into the theme directory and run npm install. After that you can run npm run dev:css – this will only compile the tailwind css and has no serve function like in some projects where npm run dev usually starts a small server for you. In parallell you have a zola serve running in a different terminal window in order to see your local dev site.
Changes are applied in themes/{themename}/static/app.css
