bottom

The bottom property is used to set the vertical position on elements that have the position set to relative, fixed, absolute, or sticky. It has no effect on elements that are not positioned.

Syntax

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

div.ex {
  position: relative;
  bottom: 100px;
}
