私はこのhtml5を持っています

 <body>
         <!--[if lt IE 7]>
             <p class="chromeframe">You are using an <strong>outdated</strong> browser. Please         <a href="http://browsehappy.com/">upgrade your browser</a> or <a href="http://www.google.com/chromeframe/?redirect=true">activate Google Chrome Frame</a> to improve your experience.</p>
    <![endif]-->

         <!-- Add your site or application content here -->
         <div id="content">
             aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
        </div>

         <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
         <script>window.jQuery || document.write('<script src="js/vendor/jquery-1.9.1.min.js"><\/script>')</script>
         <script src="js/plugins.js"></script>
         <script src="js/main.js"></script>

そして私はこのcssを持っています:

 /* ==========================================================================
    Author's custom styles
  ========================================================================== */

.content { 
    display:block;
    background:url (../img/boek.jpg);
    width: 100%;
    height: 100%;
    top: 25%;
    left: 25%;
    right: 25%;
    text-align: center;
    position: fixed;
}

しかし、背景はまったく見えず、確かにページの中心にもありません。
