Comment:

 It appears that CSSLint doesn't yet support the `fr` type:
 https://github.com/CSSLint/parser-lib/issues/228

 Three options I see here:

 1. Change from error to warning, to allow bad CSS to be saved.
 2. Try to filter out errors related to `fr`, however this doesn't seem to
 help in the case of `repeat(3, 1fr)`
 3. Add checkbox to dismiss error (or use dismissible notification) to
 allow saving to go through.

 I think option 3 is the best for now, and it aligns with how we're doing
 it when editing CSS in the file editor;
