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;
}

static positioning html

/*position: static;
HTML elements are positioned static by default.

Static positioned elements are not affected by the top, bottom, left, and right properties.

An element with position: static; is not positioned in any special way; it is always positioned according to the normal flow of the page:

This <div> element has position: static;
Here is the CSS that is used:
*/
Example
div {
  position: static;
  border: 3px solid #73AD21;
}
