title: twitter bootstrap - well background color
body: <p>I'm trying to change the background color and opacity of a bootstrap well. I've got the following CSS:</p>
  
  <pre><code>.well {
      opacity: 0.9; /* opacity [0-1] */
      -moz-opacity: 0.9; /* opacity [0-1] */
      -webkit-opacity: 0.9; /* opacity [0-1] */
      background-color: blue;
  }
  </code></pre>
  
  <p>The opacity is working, but the background-color does not seem to change. Any ideas?</p>
