.xuanzhuan{animation:xz 1s linear infinite }@keyframes xz{
from {transform:rotate(0deg)}
to{transform:rotate(360deg)}
}infinite 旋转不限次数，也可以改成1，旋转一次
用css3的transition，很容易实现hover时旋转效果的：
<style>img{width:50pxheight:50pxdisplay:block-webkit-transition:0.4s lineartransition:0.4s ease-in}
img:hover{-webkit-transform:rotate(360deg)transform:rotate(360deg)}
</style>
