Set up a css formatter that *doesn't* bloat classes lists

[xdy]

Is your feature request related to a problem? Please describe.
Prettier bloats the file by setting each class on a separate line, I prefer it to be more compact.

Describe the solution you'd like
I'd like css to be consistently formatted, and less bloated.

Describe alternatives you've considered
Don't format it at all.

Additional context
For now I have disabled prettier on .css files.
