新老客户大回馈,云服务器低至5折

利用css3 transform属性刻画钟表的的刻度以及指针的角度,代码如下:

<head>
<meta charset="UTF-8">
<title>Title</title>
<style id="style">
html{height:100%;}
body{width:100%;height:100%;margin:0;display:-moz-box;display:-webkit-box; display:box; -webkit-box-align: center; -moz-box-align: center; box-align:center; -webkit-box-pack:center;-moz-box-pack:center; box-pack:center; }
.clock{ width:200px;height:200px;border:4px solid black;border-radius:50%; position:relative; }
.clock ul{ width:100%; height:100%;position:relative;margin:0;padding:0; }
.clock ul li{list-style: none; position:absolute;top:0;left:99px;width:2px; height:5px; background:gray; transform-origin: center 100px; }
.clock ul li:nth-of-type(5n+1){ left:98px;width:4px;height:10px;background:black;}
.hour{ width:8px; height:60px; border-radius:4px; position:absolute;left:96px;top:40px; background-color:black;transform-origin: center 60px;box-shadow:0 0 10px rgba(0,0,0,0.8);}          .min{width:6px;height:70px;border-radius:3px;position:absolute;left:97px;top:30px;background-color:#2b2b2b;transform-origin: center 70px;box-shadow:0 0 10px rgba(0,0,0,0.6);}           .sec{width:4px;height:80px;border-radius:2px; position:absolute;left:98px;top:20px;background-color:red;transform-origin: center 80px;box-shadow:0 0 10px rgba(255,0,0,0.5);}
     .center{width:16px;height:16px;box-shadow:0 2px 5px rgba(0,0,0,0.5); border-radius:50%;position:absolute;left:92px;top:92px;background-image: radial-gradient(white,gray);}
   </style>
</head>
<body>
  <div class="clock">

      var liStr = "";
      var styleStr = "";
      for(var i=0;i<60;i++){
        styleStr += '.clock ul li:nth-of-type('+(i+1)+'){transform: rotate('+i*6+'deg);}';

      oUl.innerHTML = liStr;
      var oHour = document.getElementById("hour");

      var oSec = document.getElementById("sec");
      function getTime(){

        oMin.style.transform = 'rotate('+tranM+'deg) translateZ(-1px)';
        oHour.style.transform = 'rotate('+tranH+'deg) translateZ(-1px)';
       }
      setInterval(getTime,1000);
       getTime();
