ScrollReveal.js – Declarative on-Scroll Reveal Animations

ScrollReveal.js is a simple way to create and maintain how elements fade in, triggered when they enter the viewport. It helps you to build declarative on-scroll reveal animations for your websites. By adding a data-scrollreveal attribute to an element, it will automatically be revealed (using default values) as soon as the element is within the viewport. It is released under MIT License.
