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
