border-style | 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 style. 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 border style values. The number of values determines which sides receive the assigned style.
CSS Syntax
    border-style: borderStyle {1,4}
Value
Style values are constants that are associated with specific ways of rendering border lines. Not all browsers recognize all of the values in the CSS recommendation. Style support is as follows. The precise manner in which browsers interpret the definitions of the style values is far from universal. Figure 11-1 shows a gallery of all styles as rendered by Internet Explorer 6 for Windows, Explorer 5 for Macintosh, and Netscape 6. Do not expect the exact same look in all browsers.

For Navigator 4, you may apply one style value only. In Internet Explorer and Netscape 6, this attribute accepts one, two, three, or four space-delimited borderStyle values, depending on how many and which borders you want to set with specific styles. Value quantities and positions are interpreted as shown in the following table.

--- | --- | --- | --- | ---
dashed | 6 | 5.5 | 4 | 1
dotted | 6 | 5.5 | 4 | 1
