In this chapter, we looked at a few different ways of reacting to our site visitors who scroll down the page. We created a parallax effect by animating the position of layers of content at different speeds as we scroll down the page. We created a horizontal animation that reacts to scrolling. Finally, we created a navigation bar that not only updates as we scroll down the page but also allows us to easily move to the different areas of the page. Not too shabby. Next up, we'll look at some ways to make forms nicer-looking as well as easier for our site visitors to work with.
