How do i do this?

Hi Forum

Im looking for some help or to be sent in the right directions I have to design a music band website and would very much like to do a transition between different pages - I’m
enclosing an example done by nicktoonsnetwork - basically the concept
that i have is that the band will be playing in different rooms of a
house and each time you go to a new room you have to pass through all
the other rooms ( its just like tween from one room to the next) do
you think that this is possible? i have seven rooms!!!

any help or if you can point me in the right direction i would be so grateful
