第二步：
在<body>区添加以下代码
<div id="c0" style="position:absolute;right:6;top:6; z-index:2;"> 
   </div>
        <div id="c1" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>1</b></div>
        <div id="c2" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>2</b></div>
        <div id="c3" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>3</b></div>
        <div id="c4" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>4</b></div>
        <div id="c5" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>5</b></div>
        <div id="c6" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>6</b></div>
        <div id="c7" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>7</b></div>
        <div id="c8" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>8</b></div>
        <div id="c9" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>9</b></div>
        <div id="c10" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>10</b></div>
        <div id="c11" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>11</b></div>
        <div id="c12" style="position:absolute;left:20;top:-20; z-index:5;font-size:11px;"><b>12</b></div>
        <div id="ob0" style="position:absolute;left:-20;top:-20;z-index:1">  </div>
        <div id="ob1" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>
        <div id="ob2" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>
        <div id="ob3" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>
        <div id="ob4" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>
        <div id="ob5" style="position:absolute;left:-20;top:-20;z-index:8"> <font size="+3" color="#0000FF"><b>.</b></font></div>
        <div id="ob6" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
        <div id="ob7" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
        <div id="ob8" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
        <div id="ob9" style="position:absolute;left:-20;top:-20;z-index:7"> <font size="+3" color="#00FFFF"><b>.</b></font></div>
        <div id="ob10" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>
        <div id="ob11" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>
        <div id="ob12" style="position:absolute;left:-20;top:-20;z-index:6"> <font size="+3" color="#F30000"><b>.</b></font></div>




第三步：
修改<body>标签，添加相关事件
<body bgcolor="#fef4d9" onLoad="ob(),setNum(),setInterval('timer()',100);setInterval('runClock()',100)">
