CSS pseudo-Class selector

CSS pseudo-class selectors: styles to add to hyperlinks (different states of links and styles)

A hyperlink that has four states:

Normal state (: link): The mouse is not placed on the previous linked style.

Put on status (: hover): The style when the mouse is placed over the link.

Activation status (: Active): Hold down the left mouse button to not release the style, this state is particularly short.

Visited status (: visited): Press the left mouse button, and bounce, then the style effect.

In normal work, the following wording is used to add a different style to the link:

A:link, a:visited{color: #444; text-decoration:none;} The normal state and the visited state are combined.

a:hover{color: #990000; text-decoration:underline;} "Mouse on" to do a single effect
