Javascript实现的LCD电子时钟，可以显示当前时间，年\月\日等等信息

在网页<head>区添加以下代码

<Style type="text/css">

.clock
    {
border-top      : black 1px solid;
border-left     : black 1px solid;
border-right    : black 1px solid;
border-bottom   : black 1px solid;
color           : black;
font-family     : verdana;
border-collapse : collapse;
background-color: #a6a98d;
    }

.time
    {
font-size       : 100px
    }

.clock TD 
    {
border-top      : black 1px solid;
border-left     : black 1px solid;
border-right    : black 1px solid;
border-bottom   : black 1px solid;
border-collapse : collapse
    }
