How to create one page site?

To create a page with sections, seems to be possible with the smart page building tool.

(1) But how to create side to side running background for these sections?

(2) How to navigate these section-top from the menu? (Without code hancking. :)

(3) How to fix/hide the menu at the top while scrolling the page? (Without code magic.)

As an example it can be seen: http://www.websitex5.com/en/

Hope there is an answer! I hope websitex5 uses websitex5 to create it-self!
