css make background image position fixed and scroll content up

Question

How can we do something similar as done in this example http://theme.nileforest.com/html/mazel-v1.1/home-text-rotator1.html

They are keeping background image fixed and contents over it. I am not sure how they are doing it it possible with css only or they are using java-script.

I am still trying to figure it out.

Any fixed example or pointer would be great to start with
