有些時候我們需要提示客戶“DO NOT COPY”, 就像在MS Word中所做的那樣，昨天遇到這樣的case，就嘗試用CSS+DIV解決：
頁面代碼如下，還有一些地方需要改進，比如調整浮水印的大小以覆蓋全部頁面等：
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Untitled Page</title>
<style type="text/css">
.bg
{
width: 200%;
height: 200%;
margin: 0px;
position: absolute;
z-index: 100;
top: 0px;
left: 0px;
background-color: #000;
filter: alpha(opacity=5);
-moz-opacity: 0.05;
opacity: 0.05;
font-size: 159px;
color: White;
}
</style>
</head>
<body>
<div class="bg">
<br>
<br>
DO NOT COPY!!</div>
<div style="color: Black">
