General tips for semantically cleaning up HTML, CSS & JS?
As I've gotten deeper into using jQuery with various sites I've worked on, I've found that I can get lost on whether a class attribute value is appended to an element in the DOM in order to attach an actual CSS style, or to bind an event to it.
