I saw a really cool feature on a site and I want to try to replicate it, but I am having issues figuring out how I could structure it. If you go to the link I provided, you will see that if you scroll your mouse one time it will go to the next div and the previous one will animate out and then then the new one in. I am sure I could figure out the animation, but what I can't figure out is how I would make the window recognize that a scroll means go to the next div. Usually you have to scroll quite a ways for an animation like this to take place.
Does anyone know how I could do this?
