This doesn't work in IE6 or 7:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Title</title>
<style type="text/css">
N {display: block}
</style>
</head>
<body>
<div>
<N>element1</N>
<N>element2</N>
<N>element3</N>
<N>element4</N>
</div>
</body>
</html>
however, it does if I replace the N tags with A tags.
Does IE have a problem with styling non-HTML tags? Or is it something else?
