Re: confused about ‘relative’ and ‘absolute’ position !

I don’t know whether Chris explains this bit in the video @Paulie_D posted, but because (as you will learn) absolutely positioned elements are no longer part of the document flow, it is important to set a z-index when you want to interact (_e.g._, click an anchor link, add hover effects to different elements, etc.) with those elements. For this reason, I would also suggest learning about the CSS property z-index (if, of course, you don’t know about it already).
