Values:

[ <border-width> || <border-style> || <border-color> ] | inherit

Initial value:

Refer to individual properties.

Applies to:

All elements.

Inherited:

No.

Computed value:

As specified.

Description:

This is a shorthand property that defines the width, color, and style of an element’s border. Note that while none of the values are actually required, omitting a border style will result in no border being applied because the default border style is none. Versions of IE/Win previous to IE5.5 do not apply borders to inline elements.

Examples:

h1 {border: 2px dashed olive;}
a:link {border: blue solid 1px;}
p.warning {border: double 5px red;}

Supported by:

Firefox, Internet Explorer, Opera, Safari.
