#badge {

I really like this challenge, as it involves attention to detail and revising and refactoring. But we use an id for the badge and typically applicants will be marked down for use of ids in css. The rights and wrongs of this are a matter on which reasonable people may disagree, but the fact remains we should train people to instinctively choose the lowest level of specificity possible according to the rule of least power.

So I think we should revise this to remove the #id and start as we mean to go on.
