title: How to access the iframe element selector?
body: <p>I have an HTML page which has a child HTML which gets generated dynamically. I want to change the styles of few child HTML elements,but I'm not able to access any of the child HTML elements</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
  link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"&gt;
  &lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap-theme.min.css"&gt;
  &lt;link rel="stylesheet" href="new.css"&gt;
  &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"&gt;&lt;/script&gt;
  &lt;script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"&gt;&lt;/script&gt;
  
  &lt;body&gt;
   &lt;iframe id="cartoonVideo" src="http://www.youtube.com/embed/ABCDEFGH" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;
  
  **Child html gets generated here** 
  
  #document
  &lt;!DOCTYPE HTML&gt;
  &lt;head&gt;
  link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"&gt;
  &lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap-theme.min.css"&gt;
  &lt;link rel="stylesheet" href="new.css"&gt;
  &lt;/head&gt;
  &lt;body&gt;
  &lt;div class="access"&gt;&lt;/div&gt;
  &lt;/body&gt;
  &lt;/html&gt;
  
  
  &lt;/body&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>How do I access the child HTML div which has class as access. Either through CSS or any JavaScript or JQuery methods?</p>
