While working on this: http://groups.google.com/group/jquery-en/browse_thread/thread/7cbc9fb45f7dc133 , I've tried to come up with a way to read attributes out of a CSS class, even if that class isn't applied to any element. No luck so far.
Any jQuery pro's want to take a crack at it? Storing attributes for animations in CSS - as opposed to JavaScript - would lean to much cleaner code.
