animation属性是一个简写属性，用于在一个属性中设置：animation-name(动画名称）；animation-duration( 动画持续时间)；animation-timing-function(运动曲线)；animation-delay(动画延时)；animation-iteration-count(播放次数)；animation-direction(是否反方向)六个动画属性。如果一个动画设置了：animation-name:mymoving;animation-duration:3s；animation-timing-function:ease-in；animation-delay:1s；animation-iteration-count:infinite；animation-direction:alternate;我们可以如何进行简写？

A. animation: mymoving 3s ease-in 1s infinite alternate;
B. animation-name: mymoving 3s ease-in 1s infinite alternate;
C. @keyframes: mymoving 3s ease-in 1s infinite alternate;
D. animation-duration: mymoving 3s ease-in 1s infinite alternate;
