These are actually buttons that should be in a buttons less file or something, which we don't currently have in webmaker.org. I agree they should be more generic, although I think the base font size in this case shouldn't affect the size of the buttons, since they are supposed to be a fairly controlled/non-responsive size. But yeah, let's file a ticket for doing a ui/buttons.less for webmaker.org similar to what popcorn maker has?
