.trans-rotate{
    -webkit-transition: transform .25s linear;
    -moz-transition: transform .25s linear;
    -o-transition: transform .25s linear;
    transition: transform .25s linear;
}/* 加上这个样式后，才会在0.25秒内旋转完毕。否则只会显示立刻旋转完的结果 */

.btnbg:hover{transform:rotate(360deg);}    /* 鼠标移上去后，旋转*/

　　在需要旋转的元素上加上 class="btnbg trans-rotate"
