步驟一 :
將以下程式碼複製 , 貼在網頁原始檔HTML<head> 與 </head> 之間 .
<STYLE>.spanstyle {
COLOR: #0066ff; FONT-FAMILY: Tahoma; FONT-SIZE: 10pt; FONT-WEIGHT: normal; POSITION: absolute; TOP: -50px; VISIBILITY: visible
}
</STYLE>

</SCRIPT>

<SCRIPT language=javascript>

document.write("</span>");
}

if (document.layers) {

}
document.onmousemove = handlerMM;
</SCRIPT>

<SCRIPT language=javascript>
function pageonload() {
makesnake();
window.setTimeout("pageonload();", 2);
}
</SCRIPT>

步驟二 :
將以下程式碼複製 , 貼在網頁原始檔HTML <body> 之內 .
onload=javascript:pageonload()
