See pic. Basically, when the user clicks on the buttons on the Home page, the corresponding page will be shown. However, I want it to load without refreshing the entire browser window. I think this is called Ajax right?

If so, where should I get started with this? What frameworks should I use which will be easiest to do and setup? All I need is to load pages in this manner, nothing fancy or extra.

Tks!
