CSS bottom Property

Example

Set the bottom edge of an image to be 5px above the bottom edge of the element:


Property Definition and Usage

For absolutely positioned elements, the bottom property sets the distance higher/lower than the bottom edge of the containing element.

For relatively positioned elements, the bottom property sets the distance higher/lower than the bottom edge of its normal position.

Note: If "position: static", the bottom property has no effect.

Explanation: For static elements, it is auto; for length values, it is the corresponding absolute length; for percentage values, it is the specified value; otherwise, it is auto. For relatively positioned elements, if both bottom and top are auto, their computed values are both 0; if one of them is auto, it takes the opposite value of the other; if neither is auto, bottom takes the opposite value of top.
