用CSS为网页加上水印(add water mark to your page via CSS)

有些时候我们需要提示客户“DO NOT COPY”, 就像在MS Word中所做的那样，昨天遇到这样的case，就尝试用CSS+DIV解决：

 

 页面代码如下，还有一些地方需要改进，比如调整水印的大小以覆盖全部页面等：

 

 

<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">
        Write your contents here用CSS为网页加上水印(add water mark to your page via CSS)<br />

    </div>
</body>
</html>
