title: How to put a background image on a Bootstrap form?
body: <p>I'm trying to put a background image on my form (like behind the text and inputs, just like a background image of my web site), using the Bootstrap framework but the image appears at the bottom and I want it inside the "container". </p>
  
  <p>My code is something like this:</p>
  
  <pre><code>&lt;div class="container"&gt;
      &lt;div class="thumbnail"&gt;
          &lt;form....&gt;
              &lt;fieldset&gt;
              .
              .
              .
          &lt;/form&gt;
          &lt;img src="cs.jpg" class="img-responsive"&gt;
      &lt;/div&gt;
  &lt;div&gt;
  </code></pre>
