What feature is this in online code

[jonpeter]

Given any website. When you click on a button and then a new div appears with new information without requiring the browser to refresh the page?

Also how would I enact this feature in HTML/CSS or JavaScript?

Also, Happy Early Thanksgiving!

If the "new information" you are referring to is not in the source code of the page that has already been loaded, then it is being done via AJAX. Asynchronous JavaScript and XML.

This info on the W3C's site should be good to get you started with AJAX.
