thanks for the tip.
so

function getStyle(el,styleProp)
{
var x = document.getElementById(el);
if (x.currentStyle)
var y = x.currentStyle[styleProp];
else if (window.getComputedStyle)
var y =
document.defaultView.getComputedStyle(x,null).getP ropertyValue(styleProp);
return y;
}

alert(getStyle("ha", "marginTop"))

will show "auto" in IE and an empty string in Firefox. If I add a
style for <p> as margin: 10px, then IE will show 10px and Firefox will
not show anything.
