title: How to scroll xx pixels or % at once
body: <p>I am building a website and I want to customize the scrolling. If the user scrolls I want them to scroll down 100% at once like in this website: <a href="http://onlinedepartment.nl/" rel="nofollow">http://onlinedepartment.nl/</a></p>
  
  <p>EDIT: I already managed smooth scrolling with anchor points. But I want it to work on mousescroll too</p>
  
  <p>Any ideas? Thanks in advance</p>
