The margin property sets the margins of an element by specifying between one and four values, where each value is a length, a percentage, or auto. Percentage values refer to the parent element's width. Negative margins are permitted.

If four values are given, they apply to top, right, bottom, and left margin, respectively. If one value is given, it applies to all sides. If two or three values are given, the missing values are taken from the opposite side.

Examples of margin declarations include:

BODY { margin: 5em } /* all margins 5em */
P { margin: 2em 4em } /* top and bottom margins 2em,
left and right margins 4em */
DIV { margin: 1em 2em 3em 4em } /* top margin 1em,
right margin 2em,
bottom margin 3em,
left margin 4em */

Note: adjoining vertical margins are collapsed to use the maximum of the margin values. Horizontal margins are not collapsed.

Using the margin property allows one to set all margins; alternatively, the properties margin-top, margin-bottom, margin-left, and margin-right may be used.
