Remarks

As of Microsoft Internet Explorer 4.0 or later, you can specify possible length values relative to the height of the element's font (em) or the height of the letter "x" (ex).

In Microsoft Internet Explorer 3.0, the specified margin value is added to the default value of the object. In Internet Explorer 4.0 or later, the margin value is absolute. The margin properties do not work with the td and tr objects in Internet Explorer 4.0, but they do work in Internet Explorer 3.0. To set margins in the cell for Internet Explorer 4.0 or later, apply the margin to an object, such as div or p, within the td.

As of Microsoft Internet Explorer 5.5, this property applies to inline elements. With earlier versions of Windows Internet Explorer, inline elements must have an absolute position or layout to use this property. Element layout is set by providing a value for the height property or the width property.

For inline elements, the value of this property is used to compute the border area of a surrounding inline element, if present. This value does not contribute to the height of a line.

Negative margins are supported, except for top and bottom margins on inline objects.

Examples

The following examples use the margin-bottom attribute and the margin-bottom property to change the margin of the object.

This example uses the img object as a selector to set the bottom margin on images to 2 centimeters.

<STYLE>
    IMG { margin-bottom:2cm }
</STYLE>

This example uses inline scripting to set the bottom margin of the image to 1 centimeter when an onmouseover event occurs.

<IMG src="sphere.jpg"onmouseover="this.style.marginBottom='1cm'">
