Animate elements as they scroll into view.

Introduction

ScrollReveal is a JavaScript library for easily animating elements as they enter/leave the viewport. It was designed to be robust and flexible, but hopefully you’ll be surprised below at how easy it is to pick up.

Installation

Browser

A simple and fast way to get started is to include this script on your page:

<script src="https://unpkg.com/scrollreveal"></script>

This will create the global variable ScrollReveal

Be careful using this method in production. Without specifying a fixed version number, Unpkg may delay your page load while it resolves the latest version. Learn more at unpkg.com

Module

npm install scrollreveal

CommonJS

const ScrollReveal = require('scrollreveal')

ES2015

import ScrollReveal from 'scrollreveal'

Usage

Installation provides us with the constructor function ScrollReveal(). Calling this function returns the ScrollReveal instance, the “brain” behind the magic.

ScrollReveal employs the singleton pattern; no matter how many times the constructor is called, it will always return the same instance. This means we can call it anywhere, worry-free.

There’s a lot we can do with this instance, but most of the time we’ll be using the reveal() method to create animation. Fundamentally, this is how to use ScrollReveal:

<h1 class="headline">
	Widget Inc.
</h1>

ScrollReveal().reveal('.headline')
