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
bottomproperty sets the bottom edge of an element to a unit above/below the bottom edge of its nearest positioned ancestor. - If position: relative; - the
bottomproperty makes the element's bottom edge to move above/below its normal position. - If position: sticky; - the
bottomproperty 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
bottomproperty has no effect.
