title: background-image in MVC4 not work
body: <p>I am using basic template for mvc 4.I want set background image for my div element.My stylesheet located in "~/Content" directory.Here is part of my .cshtml file where I am trying direct specify image without css:</p>
  
  <pre><code>        &lt;div id="add_image" class ="image_bar" style="background-image:url(add.jpg)" &gt;&lt;/div&gt;
  </code></pre>
  
  <p>Here is my css:</p>
  
  <pre><code>#add_image {
      background-image:url('~/add.jpg');
  }
  
  #add_image:hover {
      background-image:url('~/addhover.jpg');
  }
  .image_bar {
      width:40px;
      height:40px;
  }
  </code></pre>
