Element.offsetTop (Property)

The Y coordinate of the HTML element.

Availability:

JScript - 3.0

Internet Explorer - 4.0

Opera - 5.0

Property/method value type: Number primitive

JavaScript syntax: IE myElement.offsetTop

An offset value in the vertical access from the origin of the parent to the top of the receiving Element object. This value is read-only.

The offsetParent property contains a reference to the parent object that the relative positions are measured with respect to.

Warnings:

The offset properties are implemented very inconsistently across platforms and versions of MSIE. Use them with caution. In any case, they are available for read access only so they are of limited use in position control.

ReadOnly.
