1、在<head>与</head>之间加入代码：
<style type="text/css">
.spanstyle {
position:absolute;
visibility:visible;
top:-50px;
font-size:9pt;
color: #8000FF;
font-weight:bold;
}</style>
2、在<body> 后加上 onLoad="makesnake()"
如： <body onLoad="makesnake()">
3、在<body>与</body>之间加入：
<script>
var x,y
var step=20
var flag=0
var message="艺术天地……"
message=message.split("")
var xpos=new Array()
for (i=0;i<=message.length-1;i++) {
xpos[i]=-50}
var ypos=new Array()
for (i=0;i<=message.length-1;i++) {
ypos[i]=-50}
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[i]=xpos[i-1]+step
ypos[i]=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[i]
thisspan.posTop=ypos[i] } }
else if (flag==1 && document.layers) {
for (i=message.length-1; i>=1; i--) {
xpos[i]=xpos[i-1]+step
ypos[i]=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[i]
thisspan.top=ypos[i]} }
var timer=setTimeout("makesnake()",30)}
</script>
<script>
for (i=0;i<=message.length-1;i++) {
document.write("<span id='span"+i+"'class='spanstyle'>")
document.write(message[i])
document.write("</span>")}
if (document.layers){
document.captureEvents(Event.MOUSEMOVE);}
document.onmousemove = handlerMM;
</script>
