Better capitals

So, a couple of weeks ago, as I was working on a LaTeX document, I stumbled upon a little known tipographic rule. Simply put: text in ALL CAPITALS should have a subtly wide letter spacing. This is my take using CSS. I know, it's simple, but it's a nice touch that improves readability.
