Dear reader,

I've got multiple questions dealing with unknowns.
First of al: I don't use any unknowns myself, though i haven't got a clue
what they do to begin with.
But i do find them in lots of stylesheets, sometimes in large quantities.
So can someone shine some light on this and explain what its for? :

A:active {
 color: #6699ff
}
A:unknown {
 color: #6699ff
}

Whats the point of using unknowns in stylesheets?
Is it useful to begin with?
If so what will it do?
Which browsers uses them or perhaps need them?

As allways, thanks in advance.


Regards,
