A crossbrowser example on how to change the background color of the document contained in an iframe:
The contentDocument property returns the Document object generated by a frame or iframe element.
This property can be used in the host window to access the Document object that belongs to a frame or iframe element.
Note: Because of security reasons, the contents of a document can be accessed from another document only if the two documents are located in the same domain.
The contentDocument property is supported in all major browsers.
Note: Internet Explorer 8 (and higher) supports the contentDocument property only if a !DOCTYPE is specified. For earlier versions of IE, use the contentWindow property.
| Return Value: | A reference to the document object. If there is no document, the returned value is null |
