Parallax scrolling with plain CSS3

Hi fellow developers, i've always been fascinated by sites that did parallax scrolling. Since there isn't a course on teamtreehouse on how to implement one, i've decided to look for a tutorial on how to implement one. I'm trying to do up a simple site by implementing what was taught in the tutorial, however, i've some trouble understanding what the author has written.

Would someone be able to explain to me what does it mean when he said that "Defining the height and perspective style properties of an element will lock the perspective to its centre, creating a fixed origin 3D viewport.'
