title: Bootstrap 3 div over responsive image
body: <p>I'm trying to have a full width <code>&lt;div&gt;</code> over an image, with text inside it, so that the text goes over the image itself. The grid and the image is responsive, and I can't get the <code>&lt;div&gt;</code> to be 100% of the grid.</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-html lang-html prettyprint-override"><code>&lt;link href="http://netdna.bootstrapcdn.com/bootstrap/3.0.3/css/bootstrap.min.css" rel="stylesheet"/&gt;
  &lt;div class="container"&gt;
      &lt;div class="row"&gt;
          &lt;div class="col-md-6"&gt;
              &lt;img src="http://lorempixel.com/300/300/cats" class="img-responsive portfolio_frontpage" alt=""&gt;
              &lt;div class="portfolio_description"&gt;
                  &lt;h2&gt;Heading&lt;/h2&gt;
                  &lt;p&gt;Some random tekst blablabla&lt;/p&gt; &lt;span class="read_more"&gt;&lt;/span&gt;
              &lt;/div&gt;
          &lt;/div&gt;
          &lt;div class="col-md-6"&gt;
              &lt;img src="http://lorempixel.com/300/300/cats" class="img-responsive portfolio_frontpage" alt=""&gt;
              &lt;div class="portfolio_description"&gt;
                  &lt;h2&gt;Heading&lt;/h2&gt;
                  &lt;p&gt;Some random tekst blablabla&lt;/p&gt; &lt;span class="read_more"&gt;&lt;/span&gt;
              &lt;/div&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;!-- /.row --&gt;
  &lt;/div&gt;
  &lt;!-- /.container --&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p>As you can see, I want the <code>portfolio_desciption</code> to be over the image, fill the width of the grid <code>col-md-6</code> and have a white background.</p>
  
  <p>Any suggestions on how my CSS should be composed?</p>
