title: Unable to apply CSS for body of a HTML document
body: <p>I am unable to apply a background image in my HTML document using the following code in CSS:</p>
  
  <pre><code>body
      {
          text-align:center;
          background-image:url('C:\wamp\www\marks display\WI71.jpg');
      }
  </code></pre>
  
  <p>I also searched for it, but I found, the above declaration is true but unable to execute it. Why is this happening?</p>
