The margin-bottom property sets the bottom margin of an element by specifying a length or a percentage. Percentage values refer to the parent element's width. Negative margins are permitted.

Example:

DT { margin-bottom: 3em }

Note: adjoining vertical margins are collapsed to use the maximum of the margin values.
