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 IHTMLCurrentStyle::position or layout to use this property. Element layout is set by providing a value for the IHTMLCurrentStyle::height property or the IHTMLCurrentStyle::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

In the following example, three div elements specify IHTMLCurrentStyle::height, IHTMLCurrentStyle::width, and IHTMLCurrentStyle::backgroundColor values. The second div element also specifies a IHTMLCurrentStyle::marginTop value of 10px.

<div id="blue"></div>
<div id="yellow"></div>
<div id="green"></div>

#blue {
   background-color: #00A4EF;
   height: 50px;
   width: 50px;
}
#yellow {
   background-color: #FFB900;
   height: 50px;
   width: 50px;
   margin-top: 10px;
}
#green {
   background-color: #7FBA00;
   height: 50px;
   width: 50px;
}

The following image shows the result. The second div element has a top margin of 10 pixels.
