Answer: 
You might want to look into jQuery UI Dialogue <http://jqueryui.com/dialog/>

Names for that are: pop up, modal box, and dialogue box, though I'm sure there are plenty of others.
[Create a pop up window with HTML](http://www.quackit.com/html/codes/html_popup_window_code.cfm)

Probably not the best place to point. But it will show/give you the code to create a popup window. 

Customization of that is up to you.
