border Attribute | border Property
-----------------------------------------------------------
---------------------
Sets or retrieves the properties to draw around the object.
Syntax
HTML { border : sBorder }
Scripting object.style.border [ = sBorder ]
Possible Values
sBorder 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 borderWidth
property.
style Any of the range of style values available to the
borderStyle property.
color Any of the range of color values available to the
borderColor property.
The property is read/write. The property has a default
value of medium 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
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.
As of Microsoft® Internet Explorer 5.5, this property
applies to inline elements. With earlier versions of
Internet Explorer, inline elements must have an absolute
position or layout to use this property. Element layout is
set by providing a value for the height property or the
width property.
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.
Show Example
<HEAD>
<STYLE>
.applyBorder { border:0.2cm groove orange }
.removeBorder { border:none }
</STYLE>
</HEAD>

<TD onmouseover="this.className='applyBorder'"
onmouseout="this.className='removeBorder'">
<IMG src="sphere.jpg"></TD>

property.
<TD onmouseover="this.style.border='0.2cm groove pink'">
