CSS bottom Property

Example

Set the bottom edge of the <div> element to 10px above the bottom edge of its nearest parent element with some positioning:

div.absolute {
  position: absolute;
  bottom: 10px;
  width: 50%;
  border: 3px solid #0054ff;
}

Definition and Usage

The bottom property affects the vertical position of a positioned element. This property has no effect on non-positioned elements.

• If position: absolute; or position: fixed; - the bottom property sets the bottom edge of an element to a unit above/below the bottom edge of its nearest positioned ancestor.
• If position: relative; - the bottom property makes the element's bottom edge to move above/below its normal position.
• If position: sticky; - the bottom property behaves like its position is relative when the element is inside the viewport, and like its position is fixed when it is outside.
• If position: static; - the bottom property has no effect.

Default value:	auto
