title: How to darken a background using CSS?
body: <p>I have an element with text in it. Whenever I decrease the opacity, then I decrease the opacity of the WHOLE body. Is there any way I can just make the <code>background-image</code> darker, and not everything else? </p>
  
  <pre><code>background-image:url('http://fc02.deviantart.net/fs71/i/2011/274/6/f/ocean__sky__stars__and_you_by_muddymelly-d4bg1ub.png');
  </code></pre>
