Syntax
Description
For absolutely positioned boxes, this property specifies how far the bottom margin edge of the box is offset above the bottom padding edge of its containing block.
For relatively positioned boxes, this property specifies how far the bottom edge of the box is offset above the position it would have had in the normal flow.
If both top and
bottom have a value other than
auto, bottom is
ignored.
Example
This style rule makes the element
with ID "logo" generate a relatively positioned box
that’s shifted ten pixels upward:
#logo {
position: relative;
bottom: 10px;
