Particles.js是一款基于HTML5 Canvas画布的轻量级粒子动画插件，可以设置粒子的形状、旋转、分布、颜色等属性，还可以动态添加粒子，效果非常炫酷，能和鼠标互动吸附或者是躲避鼠标指针。

Particles.js基于Canvas画布创建粒子原子颗粒效果

使用方法

1、该粒子动画库插件使用方法非常简单，首先要在页面中引入particles.js文件。

2、在页面中使用一个div来作为放置粒子的容器。

3、通过particlesJS.load()方法加载配置文件

particlesJS.load('particles-js', 'assets/particles.json', function() { console.log('callback - particles.js config loaded'); });

4、编写particles.json配置文件

{ "particles": { "number": { "value": 80, "density": { "enable": true, "value_area": 800 } }, "color": { "value": "#ffffff" }, "shape": { "type": "circle", "stroke": { "width": 0, "color": "#000000" }, "polygon": { "nb_sides": 5 }, "image": { "src": "img/github.svg", "width": 100, "height": 100 } }, "opacity": { "value": 0.5, "random": false, "anim": { "enable": false, "speed": 1, "opacity_min": 0.1, "sync": false } }, "size": { "value": 10, "random": true, "anim": { "enable": false, "speed": 80, "size_min": 0.1, "sync": false } }, "line_linked": { "enable": true, "distance": 300, "color": "#ffffff", "opacity": 0.4, "width": 2 }, "move": { "enable": true, "speed": 12, "direction": "none", "random": false, "straight": false, "out_mode": "out", "bounce": false, "attract": { "enable": false, "rotateX": 600, "rotateY": 1200 } } }, "interactivity": { "detect_on": "canvas", "events": { "onhover": { "enable": false, "mode": "repulse" }, "onclick": { "enable": true, "mode": "push" }, "resize": true }, "modes": { "grab": { "distance": 800, "line_linked": { "opacity": 1 } }, "bubble": { "distance": 800, "size": 80, "duration": 2, "opacity": 0.8, "speed": 3 }, "repulse": { "distance": 400, "duration": 0.4 }, "push": { "particles_nb": 4 }, "remove": { "particles_nb": 2 } } }, "retina_detect": true } 自定义参数
