Remarks

This is a composite property that specifies up to four width values, in the following order: top, right, bottom, left. If one width value is specified, it is used for all four sides. If two width values are specified, the first is used for the top and bottom borders, and the second is used for left and right borders. If three width values are specified, they are used for the top, right/left, and bottom borders, respectively. Negative margins are supported except for top and bottom margins on inline objects.

As of Microsoft Internet Explorer 4.0, you can specify 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 IHTMLStyle::position or layout to use this property. Element layout is set by providing a value for the IHTMLStyle::height property or the IHTMLStyle::width property.

For inline elements, the top and bottom values are used to compute the border area of a surrounding inline element, if present. These values do not contribute to the height of a line.

Margins are always transparent.

The below image shows the content, padding, border, and margin areas of a basic box. The red labels illustrate the edges of each of these areas.

Examples

In the following example, three div elements specify IHTMLStyle::height and IHTMLStyle::width values. The second div element uses the IHTMLStyle::margin property to set IHTMLStyle::marginTop to 5px, IHTMLStyle::marginRight to 0px, IHTMLStyle::marginBottom to 15px, and IHTMLStyle::marginLeft to -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: 5px 0px 15px -10px;
}
#green {
   background-color: #7FBA00;
   height: 50px;
   width: 50px;
}

The following image shows the result.
