It’s the perfect plugin for you if you want to … Animate based on scroll position – either trigger an animation or synchronize it to the scrollbar movement (like a playback scrub control). | Pin an element starting at a specific scroll position – either indefinitely or for a limited amount of scroll progress (sticky elements). | Effortlessly add parallax effects to your website. | Blah blah.. ScrollMagic is a Wordpress Plugin Standard Alone. You can use it only Wordpress required.
