Description Bj 2003-02-27 22:14:28 UTC 
The rule a.foo:before:hover { color: red } is invalid, while the validator 
marks it as beeing valid and incorrectly pretty prints it as a.foo:hover:before 
{ color : red; }.
Comment 1 Bj 2005-09-07 01:53:48 UTC 
Another test case is

  P:first-letter P.c { color: red; }

which is also not allowed.

Comment 3 Jukka K. Korpela 2013-04-16 03:16:32 UTC 
The rule a.foo:before:hover { color: red } passes validation, both using CSS 2.1 profile and using CSS 3 profile. So if the bug was fixed, it has now reappeared.

I noticed this when checking why p:first-line:before passes, despite being invalid. It does not pass if the two-colon syntax for pseudo-elements is used, i.e. p::first-line::before.
