基于Particles.js的粒子动态背景

js文件下载地址

页面引入js

<script src="js/particles.js"></script>

在页面中使用一个div来作为放置粒子的容器

<div id="particles"></div>

容器style设置

#particles {
    position: absolute;
    top: 0;
    width: 100%;
    z-index: -1;
    background-color: #eee;
    overflow: hidden;
    clear: both;
    height: 100%;
}

Particlesjs应用脚本

$(function () {
    particlesJS("particles", {
        "particles": {
