I built this for fun, and to remind people that CSS can do more than you think. (it should also be a nice tool to help teach adders)
While I would obviously never do something this insane in a real product, I have used CSS for surprisingly much actual logic in real code (empty states for lists, hiding controls that the user cannot use, etc).
