Question

Which selects all visited links?

(a) :valid

(b) :visited

(c) :target

(d) :selection

I have been asked this question by my school teacher while I was bunking the class.

My question is taken from Server Specific CSS in chapter Layout & Images of CSS

Answer 1

Right answer is (b) :visited

To explain: :visited selects all visited links, :valid selects all input elements with a valid value, :target selects the current active # element, ::selection selects the portion of an element that is selected by a user.
