## particles.js
### A lightweight JavaScript library for creating particles.
------------------------------
### `Demo / Generator`
<a href="http://vincentgarreau.com/particles.js/" target="_blank"><img src="http://vincentgarreau.com/particles.js/assets/img/github-screen.jpg" alt="particles.js generator" /></a>
Configure, export, and share your particles.js configuration on CodePen: <br />
http://vincentgarreau.com/particles.js/
CodePen demo: <br />
http://codepen.io/VincentGarreau/pen/pnlso
-------------------------------
### `Usage`
Load particles.js and configure the particles:
**index.html**
```html
<div id="particles-js"></div>
<script src="particles.js"></script>
```
**app.js**
```javascript
/* particlesJS.load(@dom-id, @path-json, @callback (optional)); */
particlesJS.load('particles-js', 'assets/particles.json', function() {
console.log('callback - particles.js config loaded');
});
```
