text-decoration

This property defines specific text effects. Possible values are blink, line-through, overline, underline, and none. The blink value is actually part of the CSS2 specification but is not supported in IE up to version 6. The text-decoration property is often used with the a element and its associated pseudoclasses (a:active, a:hover, a:link, and a:visited) to turn off link underlining or set different looks for hover or visited states.

Example

a {text-decoration: none;}
a:visited {text-decoration: line-through;}
a:hover {text-decoration: underline;}
.onsale {text-decoration: blink;}
.underlined {text-decoration: underline;}
.struck {text-decoration: line-through;}
