i didnt actually know how to name this...

Im wondering how can i make a page with some sort of changing inside it
and yet to keep the background intact...
like i click on a button and something moves from one place on another
and other things on the page stays there...and that should be done
without page loading all over again...

Can someone move me into right direction:)
