本文利用CSS实现大小相同、颜色深浅不一的粒子旋转加载动画，供大家参考，具体内容如下。
animation属性设置的参数：
● 设置对象所应用的动画名称：load5。
● 设置对象动画的持续时间：1.1s。
● 设置对象动画的过渡类型：
ease：动画以低速开始，然后加快，在结束前变慢。
linear：匀速。
ease-in：动画以低速开始。
ease-out：动画以低速结束。
ease-in-out：动画以低速开始和结束，相对于ease缓慢，速度更均匀。
step-start：按keyframes设置逐帧显示，第一帧为keyframes设置的第一帧。
step-end：按keyframes设置逐帧显示，第一帧为样式的初始值。
steps(<number>[, [ start | end ] ]?)：把keyframes里设置的一帧等分为几帧，start为第一次显示第一帧，end第一次显示样式的初始值，例如：steps(4,start)。
cubic-bezier(<number>, <number>, <number>, <number>)：在 cubic-bezier 函数中自己的值。可能的值是从 0 到 1 的数值。贝兹曲线限制了首尾两控制点的位置，通过调整中间两控制点的位置可以灵活得到常用的动画效果。
● 设置对象动画的循环次数：infinite（无限循环）。 将动画运行整个过程的分为0%，12.5%，25%，37.5%，50%，62.5%，75%，87.5%，100%这8个阶段，在不同的阶段运用颜色的透明度制作出不同的阴影效果。
