CSS tabs navigations using LI and having them update on the page dynamically


I am looking for a script or tutorial on how to create tabs that do not need to refresh the page or change the url when switching tabs. Is this behavior created using javascript? or ajax?

Also, what is the proper name for this kind of a tab?


Javascript :). Ajax is JS, but allows for server side action. Unless you need server side stuff (e.g. getting information from a database) then JS is the way :).
