title: fancybox iframe dimension
body: <p>In the fancybox homepage (<a href="http://fancybox.net/home" rel="noreferrer">http://fancybox.net/home</a>) there is an example that opens an iFrame dimensioned as the 75% of the screen.</p>
  
  <p>I can't get it by modifying the width and height properties on the .js file as described on the site.</p>
