Tab changing on same page

[hostfrog.com]

I think it is a javascript. But I am completely lost on how to complete this task.

I want to have about 4 or 5 tabs at the top which will change the content in the box, not the page and move the to the tab that is select (highlighted or whatever)

How can this be done?
