分享一个纯CSS写的钟表式计时器

本demo没使用JavaScript，纯CSS3实现，下面是完整代码

<html>
    <head>
        <meta charset="UTF-8">
        <title>时钟</title>
        <style type="text/css">
            .screen{

              height: 400px;
              border-radius: 50%;
              border: 3px solid black;
              margin: 200px auto;
              position: relative;
            }
            .line{

      </div>

</html>

其实很简单，就是用div结合CSS3的旋转属性把时分秒针画出来，再把刻度线等画一下；再利用CSS3的动画属性让3根针动起来即可。有兴趣的小伙伴也可以结合js代码获取当前时间并设定3根针的初始角度，让本demo变成一个实时的时钟哦~
