How to remove div in cross site div? : <p>I have an iframe youtube video, where i want to remove an div element. 
I can do it in in the console as long I manually folded out the div which I am looking for, but otherwise i am not able to find it using <code>document.getElementByClassName()</code>..</p>

<p>Is it possible via js to somehow remove an div which resides inside #document?</p>
