The property is read/write.
The property has no default value. The Microsoft Cascading Style Sheets (CSS) extension 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.
remarks this property reflects the value of the cascading style sheets (css)?b>width attribute for positioned items. this property always returns zero for nonpositioned items because "width" has meaning only when the object is positioned. if the width attribute is not set, the poswidth property returns zero. setting the poswidth property changes the value of the width but leaves the units designator for the property unchanged. unlike the width property, the poswidth property value is a floating-point number, not a string. for more information about how to access the dimension and location of objects on the page through the dynamic html（动态html，即dhtml）燿ocument object model (dom), see measuring element dimension and location.
DHTML代码范例
This example uses the posWidth property to increase the width of the first img object by 10 units. <script language="jscript">
document.all.tags("IMG").item(0).style.posWidth += 10;
</SCRIPT>
