Yeah, that's not really practical if all you're doing is an animation (that is, setting style.left and style.top repeatedly). There is no class to use, and you might be animating a large number of elements (see http://www.speich.net/computer/moztesting.php the "Slow (3D) DHTML performance compared to ie" link), or you might be positioning things in a way that can't be predetermined (e.g. following the user's mouse pointer). Neither use case is really served by a predetermined stylesheet with one class per possible position. -Boris
