42. What are pseudo-classes?

Pseudo-classes are fictional element types that do not exist in HTML. In CSS1 there is only one element type which can be classed this way, namely the A element (anchor). By creating three fictional types of the A element individual style can be attached to each class. These three fictional element types are: A as unvisited link, A as active link and A as visited link. Pseudo-classes are created by a colon followed by pseudo-class's name. They can also be combined with normal classes, e.g.:

A:link {background: black; color: white}
A:active {background: black; color: red}
A:visited {background: transparent; color: black}

<A HREF....>This anchor (or rather these anchors) will be displayed as declared above</A>

A.foot:link {background: black; color: white}
A.foft:active {background; black: color: red}
A.foot:visited {background: transparent; color: black}

<A CLASS=foot HREF....>This anchor and all other anchors with CLASS foot will be displayed as declared above</A>
