这里记录一下鄙人对于animation和transition不同之处的理解（待补充。）

animation

　　　可以实现永远循环的动画

transition

　　　可以实现hover鼠标移除移入的动画

一些注意点：（带补充。）

　　1，transform的行使对象应该是块级元素

　　2，写hover动画的时候，默然对象状态要有和hover状态中与之对应的属性，例子：如果hover里面有left:30px,对应的原始状态里面也应该有left:0;

　　3，初始状态中有rotate(90deg),再在hover里面写rotate(0deg)，hover后目标元素应该是保持其应有的状态（这里指角度），而不是其应有状态在旋转-90度，移动，缩放等同理

　　4，动画有时候会设置旋转点，而这个设置应该在本身样式里面设置，而不是在hover里面设置。
