border property

[This documentation is preliminary and is subject to change.]

Sets or retrieves the properties to draw around the object.

Syntax

border: [ width || style || <color> ]

Property values

A variable of type String that specifies or receives one or more of the following space-delimited values:

width: Any of the range of width values available to the border-width property.
style: Any of the range of style values available to the border-style property.
color: Any of the range of color values available to the border-color property.

Remarks

The border property is a composite property that sets the width, style, and color values for all four sides of an object.

You must specify a style when specifying a width or color; otherwise, the border does not render.

All individual border properties not set by the composite border property are set to their default values. For example, the default value for width is medium.

The setting border=thin is identical to border=thin none; the default value for the border color is the same as the text color if one is not initially set. So, not only does the property set width to thin, it also clears any style or color values previously set.

Setting a border to zero or omitting the attribute causes no border to be displayed. Supplying the border attribute without a value defaults to a single border.

If a color is not specified, the text color is used.

For more information about supported colors, see the Color Table.

Examples

The following examples use the border attribute and the border property to specify the composite border properties.

This example uses a call to an embedded (global) style sheet to modify the border attribute.

Copy


<HEAD>

<TR> 
    <TD onmouseover="this.className='applyBorder'"
        onmouseout="this.className='removeBorder'">
