title: Is live modification the CSS of a website possible in a iframe or DIV?
body: <p>I want to build pages that have a header bar with pages from other sites in an iframe or DIV below it.  I want to replace the CSS of the site below it with my own CSS (override it in some way; for example I may reference a blog page below it but want to change the look via CSS).  Please note these pages would only be pages whereby I would be allowed to do this based on the licensing of the site.</p>
  
  <p>Is this possible?</p>
