前言
介于很多前端小伙伴对于css3的动画的运动速度不太理解，今天就分享一款可以在线调试的贝塞尔曲线，附上链接，http://cubic-bezier.com/#.17,.67,.83,.67
规则
1. ease 对应自定义cubic-bezier(.25,.01,.25,1),效果为先慢后快再慢； 
2. linear 对应自定义cubic-bezier(0,0,1,1)，效果为匀速直线； 
3. ease-in 对应自定义cubic-bezier(.42,0,1,1),效果为先慢后快； 
4. ease-out 对应自定义cubic-bezier(0,0,.58,1),效果为先快后慢； 
5. ease-in-out 对应自定义cubic-bezier(.42,0,.58,1),效果为先慢后快再慢。
