WOW.js

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 ;-)
• You can change the settings - see below
