CSS3制作时钟

  这个效果是一个CSS3制作的时钟,不过并不是我们传统的时钟风格,分别用三块显示

  时、分、秒三个部分,而且这个DEMO中藤藤还为其加上了一个js的效果,能让这个效

  果和现实时钟的时间同步。这个效果运用到的CSS3知识点就是渐变、阴影,而最为关键

  的就是CSS3的渐变制作。

      HTML结构:

<div class="box">
  <ul>
    <li><span id="hour"></span><span>Hours</span></li>
    <li><span id="minute"></span><span>Minutes</span></li>
    <li><span id="second"></span><span>Seconds</span></li>
  </ul>
</div>

  CSS代码:

body,ul,li{ 
  padding: 0; 
  margin:0;
}
a {
  color: rgb(1, 124, 185);
  text-decoration: none;
