margin-right Attribute | marginRight Property

Internet Development Index

Sets or retrieves the width of the right margin of the object.


HTML { margin-right : sWidth } [ = sWidth ]

Possible Values

sWidthVariant that specifies or receives one of the following values.
autoDefault. Right margin is set equal to the left margin.
widthFloating-point number, followed by an absolute units designator (cm, mm, in, pt, pc, or px) or a relative units designator (em or ex). For more information about the supported length units, see CSS Length Units Reference.
percentageInteger, followed by a percent sign (%). The value is a percentage of the width of the parent object.

The property is read/write for all objects except the following, for which it is read-only: currentStyle. The property has a default value of auto. The Cascading Style Sheets (CSS) attribute is not inherited.

Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see About Dynamic Properties.


As of Microsoft® Internet Explorer 4.0 and 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 Internet Explorer 3.0, the specified margin value is added to the default value of the object. In Internet Explorer 4.0 and 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 and later, apply the margin to an object, such as div or p, within the td.

As of Internet Explorer 5.5, this property applies to inline elements. With earlier versions of Internet Explorer, inline elements must have an absolute?A HREF="../properties/position.html">position or layout to use this property. Element layout is set by providing a value for the height property or the width property.

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


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

This example uses img as a selector and margin1 as a class in an embedded style sheet to set the right margin of an image when an onclick event or ondblclick event occurs.

IMG { margin-right:1cm }
.margin1 { margin-right:2cm }
<IMG src="sphere.jpg" onclick="this.className='margin1'"
