Why doesn't the author use a :link and a :visited before they use a :hover?
I thought that was a necessary step?
w3schools (link) says this:
Note: a:hover MUST come after a:link and a:visited in the CSS definition in order to be effective!
So this means it only must come AFTER :link and :visited, it doesn't mean that they must be also be on the page? Correct?
Ok, thanks - I understand now.
