Convert absolute position to relative

Question

Is it possible to change DIV position from absolute to relative (and from relative to absolute)? DIV should remain on same place.

Answer 1

prototype.js has element.absolutize() and element.relativize which work very well.

The problem with going from relative to absolute is that element.offsetTop and offsetLeft

only give the offset of your element to its parent. You need to measure the cumualtive offset (i.e.

the offset of your element to its parent +
the offset of the parent to its parent +
the offset of its parent to its parent +

etc.)
