想做一个跟随鼠标文字的特效，在网上找到了代码，但是不知道放哪，在站里搜到一个贴子，xiyou大神你说代码放到页面底部，我放了不行啊，是不是格式摆放的问题？请教一下具体怎么弄
代码如下：
<html>
<head>
<title>跟随鼠标的字符：在鼠标后面跟着一串飘动的字符，想写什么就写什么</title><style type="text/css">
.spanstyle {
COLOR: #3366ff; FONT-FAMILY: 宋体; FONT-SIZE: 10pt; POSITION: absolute; TOP: -50px; VISIBILITY: visible
}
</style>
<script>
var x,y
var step=18
var flag=0
// Your snappy message. Important: the space at the end of the sentence!!!
var message="租天站长源码
www.zutian.net! "
message=message.split("")
var xpos=new Array()
for (i=0;i<=message.length-1;i++) {
xpos
=-50
}
var ypos=new Array()
for (i=0;i<=message.length-1;i++) {
ypos=-200
}
function handlerMM(e){
x = (document.layers) ? e.pageX : document.body.scrollLeft+event.clientX
y = (document.layers) ? e.pageY : document.body.scrollTop+event.clientY
flag=1
}
function makesnake() {
if (flag==1 && document.all) {
for (i=message.length-1; i>=1; i--) {
xpos=xpos[i-1]+step
ypos=ypos[i-1]
}
xpos[0]=x+step
ypos[0]=y
for (i=0; i<message.length-1; i++) {
var thisspan = eval("span"+(i)+".style")
thisspan.posLeft=xpos
thisspan.posTop=ypos
}
}
else if (flag==1 && document.layers) {
for (i=message.length-1; i>=1; i--) {
xpos=xpos[i-1]+step
ypos=ypos[i-1]
}
xpos[0]=x+step
ypos[0]=y
for (i=0; i<message.length-1; i++) {
var thisspan = eval("document.span"+i)
thisspan.left=xpos
thisspan.top=ypos
}
}
var timer=setTimeout("makesnake()",30)
}
</script>
</head>
<body>
<body>
<script>
<!-- Beginning of JavaScript -
for (i=0;i<=message.length-1;i++) {
document.write("<span id='span"+i+"' class='spanstyle'>")
document.write(message)
document.write("</span>")
}
if (document.layers){
document.captureEvents(Event.MOUSEMOVE);
}
document.onmousemove = handlerMM;
