Notes

justParallax.js is merely a tool to achieve a great website, here are some tips and tricks about how to use the tool.

  1. Watch the users screen size.
    When the user scrolls, the background image will move and it will repeat itself when it has reached it's max. A good solution for this is to use patterns, patterns will repeat themselves and no one will have this problem.

  2. Play around with the settings
    By playing with the settings you will create the most wonderfull effects. For example: when you combine the vertical and horizontal scroll, the background will scroll diagonal.

  3. Request new features
