Make element absolute, but do not change its position on the screen
<p>I have an element that is relative positioned on the page, relative to its parent element.</p>

<p>How can I make this element absolute with jQuery.css, but without changing the actual position on the screen? It should stay in the same place, and it should be absolute relative to the document body</p>

<p>$.css('position', 'absolute') will re-position the element </p>

<p>If it can't be done, how can I change the x,y position of this element on the screen, relative to the document body (or the browser screen)?</p>
