As someone who is not a web developer, I usually can figure out how things work on a website. However, today while browsing the site http://www.massivehealth.com/, I found myself spending quite some time trying to understand how they achieve the transitions within the page. Can someone please explain it to me? Is it something built-in with jQuery or some other advanced JavaScript technique?
If it involves JavaScript, how exactly does it function? It seems like it alters my "field of view" on the page rather than loading a new one. Is that correct? And if so, how is this effect achieved?
