Styling <hr> With CSS

Check this for a great guide on how to style the <hr> tag. Creating borders is possible through CSS, but if you want to retain support for old browsers while at the same time styling for the new, it seemed to me like the <hr> tag was the way to go. Only problem is that it looks quite dull, but in old browsers, everything looks dull!

With CSS there are plenty of ways to style it, though. I was wondering if it was possible since I haven't read anything on the topic earlier, but apparently it is, and apparently the idea that it's an element worth continued use is not mine alone. I'm tempted to copy over some of the styling techniques, but it's bet you simply check the guide!
