border-color | NN 4 IE 4 CSS 1
| Inherited: No
This is a shortcut attribute that lets you set multiple border edges to the same or different colors. Navigator 4 allows only a single value, which applies to all four edges. For Internet Explorer and Netscape 6, you may supply one to four space-delimited color values. The number of values determines which sides receive the assigned colors.
