"px" is relative to the number of pixels of the screen. "%" is relative to a certain dimension of the containing block (the tag). E.g.: #box1 { width: 50%; height: 50%; } #box2 { width: 50%; height: 50%; } <body> <div id="box1"> <div id="box2"/> </div> </body> box1 has half width and length of body and box2 has half width and length of box1.

A percentage means that depending on the width of the window, the width will change. A pixel width means that no matter the window size, the width will always be the same. One has application for fluid-layouts (%) and the other for fixed-width layouts (px)
