CSS information

Remarks

This property reflects the value of the Cascading Style Sheets (CSS) top attribute for positioned items. This property always returns zero for nonpositioned items because "top" has meaning only when the object is positioned. If the top attribute is not set, the posTop property returns zero. Use the offsetTop property to calculate actual positions within the document area.

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

Unlike the top property, the posTop property value is a floating-point number, not a string.

For more information about how to access the dimension and location of objects on the page through the Dynamic HTML (DHTML) Document Object Model (DOM), see Measuring Element Dimension and Location with CSSOM in Internet Explorer 9.
