Reveal CSS animation as you scroll down a page. By default, you should use it to trigger animate.css animations. But you can easily change the settings to your favorite animation library.
Advantages:
Smaller than other javascript parallax plugins, like Scrollorama (they do fantastic things, but can be too much heavier for simple needs)
Super simple to install, and works with animate.css, so if you already use it, that will be very fast to setup
Fast execution and lightweight code: the browser will like it
