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>height attribute for positioned items. this property always returns zero for nonpositioned items because "height" has meaning only when the object is positioned. if the height attribute is not set, the posheight property returns zero. unlike the height property, the posheight property value is a floating-point number, not a string. setting the posheight property changes the value of the height but leaves the units designator for the property unchanged. 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 posHeight property to increase the height of the first img element by 10 units. <script language="jscript">
document.all.tags("IMG").item(0).style.posHeight += 10;
</SCRIPT>
