@-webkit-keyframes loading {
0% {
-webkit-transform: rotate(0deg);
transform: rotate(0deg);
}
100% {
-webkit-transform: rotate(360deg);
transform: rotate(360deg);
}
}
有这样一段代码定义了一个动画loading,那么定义这个keyframes的时候已经加上了-webkit-前缀了,还需要在代码当中写那个不加前缀的transform吗?

It is only for compatibility with older versions of -webkit-
kernel browsers
If you are sure that the browser is old enough, you can use it directly -webkit-transform: rotate(0deg);
.
If you are sure that the browser is new enough, you can use it directly transform: rotate(0deg);
New browsers will recognize it first transform: rotate(0deg);
至于底层没有深究 但是应该是 `-webkit-transform`是对性的消耗应该是超过
`transform` 所以新旧一般都同时写上(这个等我查了相关api再补充)
