How to prevent page scrolling when using Parallax

So, let's say i have this animation:

Animation Link

I want this animation to be controlled with the mouse scroll. I used EdgeCommons and insert their parallax code. It worked. But... Take a look:

Animation link 2

As you can see, the animation is played as the user scrolls the page. The problem is that the content of the page scrolls as well. The blue box goes diagonally, while it should only go horizontally. What i want to do is to prevent the content of the page to scroll, but to keep the parallax animation.

Help????
