cross site response iframe

I’ve read through a lot of the previous posts and I believe my question has been answered. But I just wanted to get clarification to make sure.

I have a site that I want to add an iFrame to. My site is responsive. The site I want to put into the iFrame is responsive and is on a different domain. What I want to make sure of is that I can have the iFrame always be the height of the responsive content in it, so the iFrame doesn’t have to scroll, while the width still fluctuates with the width of the responsive div the iFrame is in.

I believe the answer is yes this is all possible with the pro version of the plug-in. I just want to make sure that no matter what device is used to view the site the user would have a nice looking site, and not realize that its an iFrame where they would have to scroll in it.

Thanks
