body: <p>I have created a expanding div on hover. Here is the Fiddle i created  </p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>.outer {
    height: 100px;
    width: 200px;
    border: 1px solid #000;
    overflow: hidden;
    transition: height 0.8s;
    -webkit-transition: height 0.8s;
  }
  
  .innerone {
    height: 100px;
  }
  
  .outer:hover {
    overflow: visible;
    height: 160px;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/&gt;
  &lt;script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"&gt;&lt;/script&gt;
  &lt;link href="http://getbootstrap.com/dist/css/bootstrap.css" rel="stylesheet"/&gt;
  
  &lt;div class="outer"&gt;
    &lt;div class+="innerone"&gt;
  
      &lt;br&gt;
      &lt;br&gt;
      &lt;br&gt;
      &lt;br&gt;
      &lt;br&gt;
      &lt;br&gt;
    &lt;/div&gt;
    &lt;div class+="inner"&gt;
  
  
  
      &lt;button type="button" class="btn btn-default"&gt;Default&lt;/button&gt;
    &lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
