title: Access container of parent iframe element (Iframe inside iframe)
body: <p>I have next structure of elements:</p>
  
  <pre><code>&lt;div class="container"&gt;
    &lt;iframe class="outer"&gt;
      ..
        &lt;iframe class="inner"&gt;
          actual markup with scripts here
        &lt;/iframe&gt;
    &lt;/iframe&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>using pure javascript, i've meneged to get out of "inner" iframe into outer one:</p>
  
  <pre><code>//this is HTML tag of ".outer" iframe
  var parent = window.parent.document.getElementsByTagName('html')[0];
  </code></pre>
  
  <p>but still i need to get to ".container" element in order to manipulate it.
  Can anyone tell me how to get ".container" element from script inside ".inner" element??</p>
