Description

write a test page: 

<!DOCTYPE html>
<html style="border:solid black 2px;margin:1px;padding:4px">
  <head>
	<meta charset="utf-8">
	<script src="jquery-1.8.0.js"></script>
	<script>
    $(function() {
        var a="";
        for(var i=0;i<100;i+=1) a+="aa<br>";
        $("div").html(a);
        var div = $("div")[0],
            doc = div.ownerDocument.documentElement,
            body = div.ownerDocument.body;
		window.div = div;
		window.doc = doc;
		window.body = body;
	})
	</script>
  </head>
  <body style="border:solid red 16px;margin:8px;padding:32px">
    <div id="only" style = "border:solid blue 128px;margin:64px;padding:256px">
    </div>
  </body>
</html>​

$(div).offset().top == 125, the distance from the outerline of the margin of <html> element to the outline of the border of the <div> element, minus the height of the border of <html> element.

set $(doc).css("border","");
$(div).offset().top == 109, the distance from the outline of the margin of <html> element to the outline of the border of the <div> element, minus the height of the border of "<body>" element.

set back $(doc).css("border","solid black 2px")
$(body).offset().top == 8, the distance from "the innerline of the padding of <html> element" to the outline of the border of the <div> element, minus "nothing".

What is the meaning of "relative to the document"?

The above is tested in Chrome.

In firefox,
$(div).offset().top == 111, the distance from the outerline of the margin of <html> element to the outerline of the "margin" of the <div> element, minus the height of the border of "<body>" element.

$(body).offset().top === -8, the distance from the innerline of the padding of the <html> element to the outline of the border of the <body> element, minus "the height of the border of <body> element".
