margin

Inherited: No

This is a shortcut attribute that can set the margin widths of up to four edges of an element with one statement. A margin is space that extends beyond the border of an element to provide extra empty space between adjacent or nested elements, especially those that have border attributes set. You may supply one to four space-delimited margin values. The number of values determines which sides receive the assigned margins.
