CSS Margin Properties
The CSS margin properties define the space around elements. It is possible to use negative values to overlap content. The top, right, bottom, and left margin can be changed independently using separate properties. A shorthand margin property can also be used to change all of the margins at once.
Note:
Netscape and IE give the body tag a default margin of 8px. Opera does not! Instead, Opera applies a default padding of 8px, so if one wants to adjust the margin for an entire page and have it display correctly in Opera, the body padding must be set as well!
Browser support:
IE: Internet Explorer, F: Firefox, N: Netscape.
W3C:
The number in the "W3C" column indicates in which CSS recommendation the property is defined (CSS1 or CSS2).
