String getPropertyValue(String propertyName);
propertyName
The name of the CSS attribute whose value is desired.
The string value of the named CSS attribute, or the empty string if that attribute is not explicitly set in this declaration block.
This method returns the value of the named CSS attribute as a string. Unlike getPropertyCSSValue( ), this method works with shortcut attributes as well as regular attributes. See also the various convenience properties of the CSS2Properties interface.
