第一步：把如下代码加入<body>区域中
<STYLE TYPE="text/css">
<!--
BODY{
overflow:scroll;
overflow-x:hidden;
}
.s1
{
position : absolute;
font-size : 12pt;

}
.s2
{
position : absolute;
font-size : 20pt;
color : red;

}
.s3
{
position : absolute;
font-size : 16pt;
color : gold;
visibility : hidden;
}
.s4
{
position : absolute;
font-size : 14pt;
color : lime;
visibility : hidden;
}
-->
</STYLE>
第二步：把如下代码加入<body>区域中
<DIV ID="div1" CLASS="s1">*</DIV>
<DIV ID="div2" CLASS="s2">*</DIV>
<DIV ID="div3" CLASS="s3">*</DIV>
<DIV ID="div4" CLASS="s4">*</DIV>
<script language="javascript" type="text/javascript" class="s5">
var nav = (document.layers);

if(nav) document.captureEvents(Event.MOUSEMOVE);
document.onmousemove = get_mouse;
function get_mouse(e)
{

y = (nav) ? e.pageY : event.clientY+document.body.scrollTop;
x += x_offset;
y += y_offset;
beam(1);
}
function beam(n)
{
