Surely this is easy, right? Just set the height property in your css. Well, yes and no. That’s all well and good if you know what height the elements are going to be, but quite often you might be pulling information out of a database in to the elements and you don’t know how big that information is going to be. You can’t use the overflow because that’s not the designer’s concept. No; they want three boxes on screen that all have the same height so they’re all nice and ordered and symmetrical.
