CSS bottom Property

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 #8AC007;
}

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.
