border-top-width Attribute | borderTopWidth Property

Sets or retrieves the width of the top border of the object.

Syntax

HTML { border-top-width: sWidth }

Scripting object.style.borderTopWidth [ = sWidth ]

HTML	{ border-top-width: sWidth }
Scripting	object.style.borderTopWidth [ = sWidth ]

Possible Values

sWidth String that specifies one of the following values:

medium Default width.

thin Less than the default width.

thick Greater than the default width.

width Floating-point number, followed by an absolute units designator (cm, mm, in, pt, pc, or px) or a relative units designator (em or ex). For more information about the supported length units, see CSS Length Units.

The property is read/write with a default value of medium; 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 dynamic properties.

Remarks

To use this property, inline elements must have an absolute position or layout. Element layout is set by providing a value for the height property or the width property.

The property is supported on block and replaced objects only.

Example

The following examples use the border-top-width attribute and the borderTopWidth property to specify the width of the top border.
This example uses a call to an embedded (global) style sheet to change the width of the top border to 1 centimeter when a mouse click occurs.

Sample Code
<HEAD>
<STYLE>
    TD { border-top-width:3mm }
    .changeborder1 { border-top-width:1cm }
</STYLE>
</HEAD>
<BODY>
<TABLE BORDER>
<TR>
    <TD onclick="this.className='changeborder1'"
        ondblclick="this.className=''">
        <IMG src="sphere.jpg">
    </TD>
</TR>
</TABLE>
