> Just set the properties you want the element you are using to what you want it to be. "Just". What I remember from that time was putting a button at relative 0,0 and it being at the top-left of the page in one browser, but was offset in another because that browser was adding padding/margin to <body>. I cannot say which was "correct" but it nonetheless pushed me to use normalisers, which prevented this kind of problem from ever coming up again.
