title: Iframe div to be responsive
body: <p>I have 2 <code>div</code>. One with fixed left side <code>div</code> and another <code>div</code> has <code>iframe</code> in which websites to be loaded.</p>
  
  <p>I want that <code>iframe</code> <code>div</code> to be responsive. I mean, I want all website contents to be in that particular <code>div</code> (if that particular website is responsive).</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.left_side_div {
    float: left;
    width: 150px;
    height: 100%;
    position: fixed;
    background: #f6f8f8;
  }
  
  .website_contain_main_div {
    position: relative;
    left: 151px;
  }
  
  .website_contain_main_div .website_contain_div {
    float: left;
    height: 100vh;
    min-width: 100%;
    overflow: hidden;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="left_side_div"&gt;&lt;/div&gt;
  &lt;div class="website_contain_main_div"&gt;
    &lt;div class="website_contain_div"&gt;
      &lt;iframe class="no_border" src="http://html.com/tags/iframe/" width="100%" height="100%"&gt;&lt;/iframe&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>Any help would be great.</p>
