CSS layout is awesome, except when your layout calls for a header, a footer, and columns in between. Use float, and content changes can cause columns to wrap. Use absolute positioning, and your footer can crash into your columns. Add the complexity of drag-and-drop layouts, and a new technique is needed. Enter “faux absolute positioning.” Align every item to a predefined position on the grid (as with absolute positioning), but objects will still affect the normal flow (as with float).
