title: Opacity on just jumbotron
body: <p>I want to set the jumbotron to 0.5 opacity.</p>
  
  <pre><code>    &lt;div class="jumbotron"&gt;
           &lt;table id="white" class="table table-condensed" id="table"&gt;
             &lt;tbody&gt;
             &lt;tr&gt;
               &lt;td&gt;En&lt;/td&gt;
               &lt;th&gt;1&lt;/th&gt;
             &lt;/tr&gt;
             &lt;tr&gt;
              &lt;td&gt;To&lt;/td&gt;
              &lt;th&gt;2&lt;/th&gt;
             &lt;/tr&gt;
             &lt;/tbody&gt;
           &lt;/table&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>Is there a way to do this on just the jumbotron and not the table?</p>
