A request for those that require iframes that dynamically adjust in height... For example, assume an iframe that displays a page containing tabbed content. One tab may contain content that is larger than the next tab. When switching tabs, do we therefore need to add an event listener within the content page or some function that will resend the adjusted page size to the parent, without having to reload the content page into the iframe ? I suppose the same problem would arise if font size is adjusted within the content page !! Any help by example would be greatly appreciated as I am new to programming, Please note the iframe does not need to load content from outside its domain.
