ScrollReveal: Easy scroll animations for web and mobile browsers

scrollReveal.js is plain vanilla JS library that allows you to reveal elements as they enter the viewport. It’s remarkable in that it’s only 3kb minified, that’s small. The range of effects you can choose are vast, and it uses natural language to define the animation you want to run. No need for CSS3 transition and a script to detect the current page position in the browser window. Use ScrollReveal and be done with it!
