To style the <a> elements we use Pseudo-class selectors. They must appear in the correct order. For this example, we will use a color for the general link and reverse it for the hover state. This will give users strong feedback when they roll over a link. If you want to use the same declarations for two states, they can be combined - as long as you combine "link" and "visited" or "hover" and "active".
