Some new CSS incorrectly give errors from validator.w3.org. Issues were opened in that repo, so hopefully we can remove these exceptions soon. I searched for alternative validators, but couldn't find a different one that had a simple API like this one. In order to reliably detect & handle these exceptions we unfortunately need to make the validator output parsing quite a bit more complicated.
