Hi Everyone, I am a complete newbie to Greensock and just starting to teach myself at the moment. I want to make a vertical parallax website and need a basic tutorial for how to trigger Greensock animations when the user reaches a certain point in the page whilst scrolling down. For example on reaching a DIV with ID="#Slide4" it would start to animate another DIV with the ID="Slide4Info" moving in from the side of the browser. I would want it to auto-reverse when the user scrolls back up. How do I link events to the scrollbar and how many pixels you have scrolled down? Is it better to link events to CSS elements like IDs and Classes appearing in the viewport at the bottom of the browser, or when they have reached the top of the browser? I need a complete basic tutorial in how to set up the whole page please! If anyone can point me in the right direction I would be most grateful, thanks!
