How to show one page over another in custom way I need to show one page over another for non-admin users much like 

overlay feature in Drupal7 applicable for admin users. I tried out 

overlay module and overlay UI module but not of much help.

All the overlaying pages are custom created and will be invoked on 

working page after clicking a link.

Please refer me a solution which should work across all browsers and I 

can adjust width and height of overlaying page.I want to implement this 

solution for pop up messages, warning and alert also.Please see below 

image for reference:



Need your much appreciated help.
