Using jquery, in asp.net, c# code how can I show a modal window for user like we are using on this site.

Popup : fancybox:

http://fancybox.net/

Ajax : jquery ajax:

http://api.jquery.com/jQuery.ajax/

More Reference:

http://www.dotnetspider.com/resources/40545-MODAL-PopUp.aspx

I need it to use at work.

First one: We do not want to use fancybox.
Second One: we do not want to use AJax.
Third Example is how I want to do using jquery. But this is little too complicated example.

I am wanting the simple steps I need to follow to create modal window.

Thanks.
