Sets or retrieves the bottom position of the object in the units specified by the bottom attribute.

Syntax

HTML	N/A
Scripting	object.style.posBottom [ = iBottom ]

Possible Values

iBottom

Floating-point that specifies or receives any floating-point number that uses the same length units as the bottom attribute.

The property is read/write. The property has no default value. The Microsoft Cascading Style Sheets (CSS) extension 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

This property reflects the value of the Cascading Style Sheets (CSS)?B>bottom attribute for positioned items. This property always returns zero for nonpositioned items because "bottom" has meaning only when the object is positioned. If the bottom attribute is not set, the posBottom property returns zero.

Setting this property changes the value of the bottom position but leaves the length units designator for the property unchanged.

Unlike the bottom property, the posBottom property value is a floating-point number, not a string.

For more information about how to access the dimension and location of elements on the page through the Dynamic HTML (DHTML) Document Object Model (DOM), see Measuring Element Dimension and Location.

Example

This example uses the posBottom property to set a positioned div to the bottom of the client area.

oDiv.style.posBottom = 0;
