Relatively Positioned Box: position:relative; left:26.5%; top:200px; This box comes before left gray side panel in code so left:26.5% is relative to screen edge, but it comes after the normal flow blue header panel at the top, so top:200 means 200px below that blue header panel. The text-filled div box above this box is absolutely positioned, so it's out of the normal flow, so top:200 doesn't consider it, or the grey "Ad feature image" right panel—also absolutely positioned. RELATIVE POSITIONING OFFSETS, SUCH AS LEFT AND TOP, OFFSET BOXES RELATIVE TO THEIR NORMAL FLOW ON THE PAGE.
