📝 Unwanted zero added before .<number> in CSS

[yoavbls]

Unwanted zero is added when we're using one of our utils
so

.div {
  margin-left: theme(spacing.2);  
}

become:

.div {
  margin-left: theme(spacing 0.2);  
}

which is not the intention and doesn't happen with Prettier or VSCode default formatter.

Thank you very much for your amazing work on Biome 🙏🏼

[ematipico]

The file contains invalid CSS syntax. I suppose you're using tailwind, which uses invalid/proposed syntax that isn't official yet

[yoavbls]

Yes, it is utility related to tailwind.
I would not treat [a-zA-Z].\d as a number but I understand it could happen because of the invalid syntax and out of scope.
Thank you either way 🙏🏼
