iframe broken i IE8

I have IE9 and its feature to view page in different versions is great开发者_如何学编程. But i have a problem: my page contains a iframe that loads fullcalendar (a jquery plugin). It works in IE7, Chrome and firefox, but fails in IE8 and IE9. In IE8 and IE9 the calendar is only loaded partially, only the button row on top is loaded, I cant see the actual calendar.

How come? How can i fix this?

set height=0 and width =0 to your iframe .give display-none class to that in your CSS
