Position

The position property sets what kind of positioning scheme should be used:

Property Value Description
position: static This is the normal positioning scheme. The left and top properties do not apply.
position: relative Offsets are relative to the box's normal position.
position: absolute Offsets are relative to the box's containing block.
position: fixed Offsets are the same as in the absolute model, but are fixed with respect to a particular point of reference. For example, when viewed in a browser, fixed elements won't move when scrolled.

(The position can also be set to inherit, like most other CSS properties.)
