i just spent forever trying to figure out where this unexpected 10px side margin was coming from in my columns element. at some random point, i decided to give it a class - and low and behold, there was the 10px. why o why is such default behavior hidden?
shouldn't all default settings be 0 or auto, until i choose to add some settings via a class? really frustrating to me otherwise. is there some reason for this, that i don't understand as a new user?
