For absolutely positioned elements, the top property sets the top edge of an element to a unit above/below the top edge of its nearest positioned ancestor. Note: If an absolute positioned element has no positioned ancestors, it uses the document body, and moves along with page scrolling. Note: A "positioned" element is one whose position is anything except static.

Tip: A positioned element is an element with the position property set to: relative, absolute, or fixed.
