absolute positioning css

The element is removed from the normal document flow, and no space is created
for the element in the page layout. It is positioned relative to its closest 
positioned ancestor, if any; otherwise, it is placed relative to the initial 
containing block. Its final position is determined by the values of top, right,
bottom, and left.

.element {
	position: absolute;
  	left: 0px;
  	top: 0px;
  	right: 0px;
  	bottom: 0px;
}
