body: <p>I want to create and display a self designed window on current webpage instead of popup as you can see on this page
  <a href="http://www.ericmmartin.com/projects/simplemodal-demos/#" rel="nofollow">Open the link and click first "Demo" button on that page.</a></p>
  
  <p>and the same type window appeared when I tried to put a link on this question on stackoverflow which accepted my link.</p>
