title: Resize <iframe> so that whole content just scales down or up
body: <p>I read so many posts about iframe resizing and so on, but I didn't find a solution</p>
  
  <p><strong>Problem :</strong> I want to make a webpage in iframe tag  to be shown so, as is it - I mean,if we resize the main webpage where the  tag is ,the embedded webpage has to be just scaled in or out (automatically) without losing parts of its content. Currently I need a 750x450 webpage(consisting only of a backgroung picture and some interactive buttons on it) that has to be shown in another webpage.Scrolling has to be off.</p>
  
  <p>I would be glad to hear your suggestions on how to cope with this problem.
  Thank you ! </p>
