:has pseudo-class

[aditsu]

Webcalm doesn't seem to support selectors like:

section:has(.featured) { }

(example taken from MDN docs) It says: no viable alternative at input 'section:has(.'

WebCalm perceives the following CSS description as erroneous.

@biglazycat63 please use a formatted code block instead of in image.

Also that has nothing to do with this issue (no ":has" pseudo-class). But.. we can't expect too much from a big lazy cat 😂

@aditsu BTW the reason of your issue is invalid CSS grammar. This project uses official ANTLR grammars. It should be fixed there first.
