<div class="login">	
	<h2 class="BT">Login</h2>
	<div class="zm">
<fORM action="function.php?action=login" method="post">
账号：<input type="number"  name="user">


密码：<input type="passWord"  name="password">
<p>没有账号？点击<a href="newuser.php" rel="external nofollow" >注册</a></p>
<div>
<input type="submit" value="登录"  class="dl"><input type="reset" value="重置" class="cz">
