Implement CSS4 Selectors

[timmywil]

This issue is here to track the progress of these selectors so we're prepared to support them when the spec reaches recommendation status. The list below should be updated as the spec changes.

• Subject selector :has()
• :matches()
• Reference combinators /attr/
• :any-link
• :local-link
• :blank
• :nth[-last]-child(An+B of selector)
• case-insensitive attribute comparisons [attr=value i]
• :scope

[bkardell]

subject selector will be written :has() now...
\0/
Look familiar?

@bkardell I see this isn't reflected in the spec yet: http://dev.w3.org/csswg/selectors4/#subject

[bkardell]

Yes, but it was decided in WG vote, spec changes coming soon.

[timmywil]

Updated. And thanks @bkardell!

Just a note, but "blank" keyword hasn't been accepted yet and it may change in the future.

[timmywil]

@biphobe Thanks, but it's my understanding that all of them are subject to change until the spec reaches recommendation status. Note that this issue is here to track which selectors we'll want to add in the future.

This is probably not going to happen now. Reopen if you disagree.
