Definition and Usage
For absolutely positioned elements, the bottom property sets the bottom edge of an element to a unit above/below the bottom 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.
For relatively positioned elements, the bottom property sets the bottom edge of an element to a unit above/below its normal position.
Note: If "position:static", the bottom property has no effect.
