I have been all over the internet trying to figure out how to plan an embedded youtube video in full screen automatically and have failed at every turn.
Any ideas here?
<iframe src="//www.youtube.com/embed/9ptECXgpIwk?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>
several links on the web say that the rel=0 is what makes it happen, but my understanding of that part is that it prevents related videos from being displayed when the video ends.
I don't want to use specific width and height because I want it to work on any device to the full extent of the screen size of that device.
Any help here would be greatly appreciated
