Hello everyone,

I am trying to make a background which would change as the user scroll to add some kind of "pointer" showing the different areas of my website (one page website). Here is an example similar to what I am trying to do : www.libeo.com

As you can see, the ribbon in the background "almost" follow the content of the page, jumping from one side to the other as the user scroll through the content.

I would like to know if someone could help me out with this my giving me some pointers, can this be achieved with only CSS or is jQuery a must in this case ? If someone have some examples which are simpler it would also help a lot.

I started looking into parallax, however I am not quite sure to be on the right track...

Thanks !
