offsetParent property
[This documentation is preliminary and is subject to change.]
Retrieves a reference to the container object that defines the offsetTop and offsetLeft properties of the object.
Syntax
| JavaScript | |

Property values
Type: Object
the container object.
Remarks
Most of the time the offsetParent property returns the body object.
Note In Microsoft Internet Explorer 5, the offsetParent property returns the table object for the td object; in Microsoft Internet Explorer 4.0 it returns the tr object. You can use the parentElement property to retrieve the immediate container of the table cell.
Examples
This example shows how to determine the position of a td object. Although the td object appears to the far right in the document, its position is close to the x-axis and y-axis, because its offset parent is a table object rather than the document body.
Note For Internet Explorer 4.0, this same example returns a position of 0,0 because the offset parent is the table row.
