Remarks

As of Microsoft Internet Explorer 6, when you use the !DOCTYPE declaration to specify standards-compliant mode, this property specifies the distance between the left and right edges of the content box—that is, within the IHTMLStyle::padding.

When the !DOCTYPE declaration does not specify standards-compliant mode, and with earlier versions of Windows Internet Explorer, this property includes the object's content box, plus the values of the following properties: IHTMLStyle::borderLeft, IHTMLStyle::borderRight, IHTMLStyle::paddingLeft, and IHTMLStyle::paddingRight. Subtracting the sum of the values of these properties from the value of the IHTMLStyle::width property equals the width of the parent object's content box.

To perform operations on the numeric value of this property, use IHTMLStyle::pixelWidth or IHTMLStyle::posWidth.

Examples

In the HTML and CSS examples below, the width of the three div elements are set to different values using the IHTMLStyle::width property. The width property is set to auto, the default value, for the first div, 350px for the second div, and 20% for the third div, or 20% of the width of the parent object.

<div id="one">
   Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt  
</div>
<div id="two">
   Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt  
</div>
<div id="three">
   Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt  
</div>

#one {
   width: auto;
   color: black;
}
#two { 
   width: 350px;
   color: navy;
}
#three {
   width: 20%;
   color: red;
}

You can see the result below.

This example uses inline scripting to set the width of an image when an HTMLFrameSiteEvents::onclick event occurs.

<img src="sphere.jpg" onclick="this.style.width='1cm'" ondblclick="this.style.width=''">
