particlesJS
开源在Github上:https://github.com/VincentGarreau/particles.js
具体效果
项目中有DEMO,可以下载查看效果;
如果在自己的项目中引用,建议如下:
particles.js
particles.js 是它的库,我们肯定是要引入的,app.js 是参数配置文件,我们也要引入,而 demo 中的 stats.js 就没有必要引入了。
style.css 我们也可以引入,背景颜色是在css中设置的。
基于这个模板,我们可以在上面添加我们想要实现的功能,比如说注册登录功能,需要注意的是:
用 div 来封装我们要实现的功能代码块,并且在 css 中为这个 div 设置绝对定位。
下面介绍参数配置文件 app.js 文件的使用:
particles.number.value : 粒子的数量
particles.number.density : 粒子的稀密程度
particles.number.density.enable : 启用粒子的稀密程度 (true 或 false)
particles.number.density.value_area : 每一个粒子占据的空间(启用粒子密度,才可用)
particles.color.value : 粒子的颜色 (支持16进制”#b61924”,rgb”{r:182, g:25, b:36}”,hsl,以及random)
particles.shape.type: 粒子的形状 (”circle” “edge” “triangle” “polygon” “star” “image”)
particles.opacity.value: 粒子的透明度
particles.size.anim.enable: 是否启用粒子速度(true/false)
particles.size.anim.speed: 粒子动画频率
particles.size.anim.sync: 粒子运行速度与动画是否同步
particles.move.speed: 粒子移动速度
大家可以根据这些配置文件,配置自己喜欢的背景出来,下面提供两份完整配置文件 app.js。
