找到一個有類似效果的java script，但只能出現一個方塊。
語法如下：
先在網頁的<head>和</head>之間插入這段文字：
<style>
<!--
/*Post-it note script- by javascriptkit.com
Visit JavaScript Kit (http://javascriptkit.com) for script
Credit must stay intact for use*/
#postit{
position:absolute;
width:250;
padding:5px;
background-color:lightgreen;
border:1px solid red;
visibility:hidden;
z-index:100;
cursor:hand;
}
-->
</style>
然後在網頁內容的<body>和</body>之間，最好是靠近底部以後比較好參考，放入這段文字：
<div id="postit" style="left:150px;top:150px">
<div align="right"><b><a href="javascript:closeit()">[關閉]</a></b></div>
<!--INSERT YOUR CONTENT HERE-->
