title: how to auto-size iframe in Apex?
body: <p>i'm trying to visualize an other application into my salesforce page. The problem is that the default height of the iframe that contains the other application is too short.
  I was finding how to auto resize that but i didn't find anything usefull. I do a workaround that consists in put a big height but it's a very bad solution.</p>
  
  <p>Here is my apex code page:</p>
  
  <pre><code>&lt;apex:page controller="CaseManagmentWizard" showHeader="false" sidebar="true" &gt;
  
  &lt;apex:iframe height="3000px" src="{!callCenterAPI}api/start.php?
   apiKey={!apiKey}&amp;
   username={!userIims}&amp;
  idCliente={!selectedCustomerId}&amp;
  urlOk={!callCenterURLOK}&amp; 
  urlError={!callCenterURLError}
  "&gt;&lt;/apex:iframe&gt;
  
  &lt;/apex:page&gt;
  </code></pre>
  
  <p>If I put height="100%" is the same than nothing!</p>
