I'm not really sure how to explain the function and therefor I also haven't been able to search the answer (I've tried) but as the titles says, I wanted to try out that effect when it feels like for ex. the header background isn't the one moving when scrolling but the containers that move upwards? A good example is this bootstrap template <http://wrapbootstrap.com/preview/WB0915821> 
the header and also later on the guy with the glasses, I want to try out that effect with my own website. Could anyone please help me and also tell me wahat you would call that effect/commando?
