Close button in a modal dialog
<p>I used the following which works correctly but I need to have a close button rather than closing automatically how to do that? </p>

<pre><code>$(document).ready(function() { 
     $('#app').click(function() { 
         $.blockUI({ 
             theme:     true, 
             title:    'Welcome to your page', 
             message:  '&lt;p&gt;Please have a look..&lt;/p&gt;', 
             timeout:   2000 
        }); 
    });    
}); 
</code></pre>
