title: How to Set A Webpage in gray scale color Mode while clicking a Button
body: <p>In my website I'm using a lot of images, tables, and fonts with different colors inside one div tag. When the user clicks a button the whole webpage should change to a grayscale color mode. In that mode the user should still be able to use the page.</p>
  
  <p>In IE I'm using</p>
  
  <pre><code>filter:progid:DXImageTransform.Microsoft.BasicImage(grayscale=1);
  </code></pre>
  
  <p>Which works fine, but it's not working in Mozilla Firefox.</p>
  
  <p>I found <a href="http://www.ajaxblender.com/howto-convert-image-to-grayscale-using-javascript.html" rel="nofollow">this link</a>. They only provide a script for converting an image into grayscale. But I need to convert a full <code>div</code> tag, containing many things like images, fonts &amp; so on.</p>
  
  <p>Thanks In Advance..</p>
