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:
```html
```
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](https://unpkg.com)
## Module
```bash
npm install scrollreveal
```
#### CommonJS
```js
const ScrollReveal = require('scrollreveal')
```
#### ES2015
```js
import ScrollReveal from 'scrollreveal'
```
# Usage
Installation provides us with the constructor function [`ScrollReveal()`](https://scrollrevealjs.org/api/constructor.html). 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()`](https://scrollrevealjs.org/api/reveal.html) method to create animation. Fundamentally, this is how to use ScrollReveal:
```html
Widget Inc.
```
```js
ScrollReveal().reveal('.headline')
```
