Possible Values

sStyle String that specifies or receives one of the following values.
none Default. No border is drawn, regardless of any specified borderWidth.
dotted Border is a dotted line. This value is supported on the Macintosh platform, as of Microsoft® Internet Explorer 4.01, and on the Microsoft Windows® platform, as of Internet Explorer 5.5. It renders as a solid line on Unix platforms, and on Windows systems running earlier versions of Internet Explorer.
dashed Border is a dashed line. This value is supported on the Macintosh platform as of Internet Explorer 4.01 and on the Windows platform, as of Internet Explorer 5.5. It renders as a solid line on Unix platforms, and on Windows systems running earlier versions of Internet Explorer.
solid Border is a solid line.
double Border is a double line drawn on top of the background of the object. The sum of the two single lines and the space between equals the borderWidth value. The border width must be at least 3 pixels wide to draw a double border.
groove 3-D groove is drawn in colors based on the value. The borderWidth property of the object must be specified for the style to render correctly.
ridge 3-D ridge is drawn in colors based on the value.
inset 3-D inset is drawn in colors based on the value.
window-inset Border is the same as inset, but is surrounded by an additional single line, drawn in colors based on the value.
outset 3-D outset is drawn in colors based on the value.
The property is read/write for all objects except the following, for which it is read-only: currentStyle. The property has a default value of none. The Cascading Style Sheets (CSS) attribute is not inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties.

Remarks

As of Internet Explorer 5.5, this property applies to inline elements. With earlier versions of Internet Explorer, inline elements must have an absolute?A HREF="../properties/position.html">position or layout to use this property. Element layout is set by providing a value for the height property or the width property.
