Margins can be added to push the divs away from each other.
Netscape 4 badly misinterprets margins. To hide margins from this browser, but allow them to be applied by standards compliant browsers, place the margin rules in a separate style sheet and use "@import" to link the style sheet to your html page.
We are using a shorthand rule here: "margin: 0 15px 15px 0;". Keep in mind that shorthand values are applied in a clockwise order; top, right, bottom, left.
