How do you get a browser's document.body coordinates with respect to the screen?
<p>There must be a way of finding this.
I need to figure out the coordinates of document.body with respect to a screen<img src="http://i.stack.imgur.com/o2Rpa.jpg" alt="This is as far I have got"></p>

<p>I need to figure out the coordinates for the question mark in the image. This will be the position of the document's body with respect to the screen. The image gives a description of the properties I could use.
Is it possible? </p>
