用animation实现钟表动画

HTML部分，只需要存放三个图片就可以了

       <div class="clock">
        <div class="sec"></div>
        <div class="min"></div>
        <div class="hour"></div>
  　　 </div>    

CSS部分

    <style>
        @keyframes secrun{
            0%{
                transform: rotate(180deg);
            }
            100%{
                transform: rotate(540deg);
            }
        }
        @keyframes minrun{
            0%{
                transform: rotate(180deg);
            }
            100%{
                transform: rotate(540deg);
            }
        }
        .clock{
            background-image: url(clock.png);
            background-repeat: no-repeat;
            width: 512px;
            height: 512px;
            position: relative;
        }
        .sec{
            background-image: url(second.png);
            background-repeat: no-repeat;
            width: 16px;
            height: 278px;

            top: 180px;
            left: 247px;
            transform: rotate(180deg);
            transform-origin: center 76px;  
            z-index: 3;
            animation: secrun 60s steps(60,end) infinite;
        }
        .min{
            background-image: url(minute.png);
