Pseudo-selectors are not recognized

[winstliu]

Taken from the autocomplete-css specs:

.some-class {
  .a:pseudo
}

The : is treated as the key value separator and pseudo as the property value.

I see pseudo already tokenize as property value (see image below). So is this issue should be close?

[winstliu]

Yeah, that's the bug.

It seems to match only known pseudo classes (:first-child, etc), but arbitrary ones are not identified as pseudo-classes.

I’m also seeing the same issue with several of the function-like pseudo-classes: :nth-child(), :not(), etc.
