title: CSS Color overlay with background image
body: <p>I am able to set a background image that covers a page but the green overlay does not work. What am I doing wrong? Thank you.</p>
  
  <pre><code>body {
      margin: 0 auto;
      padding: 0;
      background: url("../images/worldmap.jpg") no-repeat rgba(0,255,0,.5);
      /*background-image: url("../images/worldmap.jpg");*/
      /*background-repeat: no-repeat;*/
  }
  </code></pre>
