用div+css制作一个登录页面，首先需要做的就是将这个登录界面的布局给构想好，然后在使用div去布局出来，一般都要结合表单，因为是需要和数据库结合的，至于的具体的界面，看下代码：<html>
<head>
<meta charset="UTF-8">
<title>淘宝登录</title>
<link rel="stylesheet" type="text/css" href="../static/css/index.css" />
<script type="text/javascript">
<{if $message !=''}>
alert("<{$message}>")
<{/if}>
</script>
</head>
<body>
<div id="logo">
<div class="logotop">
<div class="yanz">
<h2>登录</h2>
<form action="logo.php" method="post">
<span style="display:blockheight:27pxwidth:27pxbackground-image:url(../static/images/logozh.jpg)float:left"></span>
<input type="text" name="uname" style="height:26px"/><br/>
<span style="display:blockheight:27pxwidth:27pxbackground-image:url(../static/images/logomm.jpg)float:left"></span>
<input type="password" name="pwd" style="height:26px"/>
<p><a href="">忘记登录密码？</a></p>
<input type="submit" value="" style="width:254pxheight:37pxbackground-image:url(../static/images/logodl.jpg)cursor: pointer"/>
</form>
</div>
</div>
</div>
</body>
</html>
这个代码有些图片的地址，需要根据要求去改，这些是我自己写的，然后就是传输的文件，action那，接受的文件也是需要定义的。
