Peony different versions

Hello,

I see different versions of the home page templates on the demo:
https://demo.mageewp.com/peony-style1/home-version-2/
https://demo.mageewp.com/peony-style1/home-version-3/
etc….

How do i set up my themes,pages, etc, to show the different versions of the demo?
Does this require additional CSS?

thanks
