在DW MX2004里做了个页面，是aspx的，使用了CSS样式文件，在DW使用浏览器预览可以正常显示效果，移到VS.NET里预览却显示不出效果，用浏览器直接输入地址也显示不正常，请问是什么原因？
以下是aspx的源码：
<%@ Page Language="c#" ContentType="text/html" ResponseEncoding="utf-8" CodeBehind="index2.aspx.cs" AutoEventWireup="false" Inherits="empty.index2" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link href="style/style2.css" rel="stylesheet" type="text/css"></link>
<title>无标题文档</title>
</head>
<body>
<div id="header">
<img class=".logo" src="style/logo.jpg" />
<img class=".advertise" src=""/>
</div>
<div id="main">
<div id="left">左边
<div id="menu">菜单栏
<ul>
<li class="submenu">子菜单</li>
<li class="submenu">子菜单</li>
</ul>
</div>
</div>
<div id="right">
<div id="content">
<div id="tabletitle">表头</div>
<div id="table">表格</div>
</div>
</div>
</div>
<div id="footer">footer</div>
</body>
</html>
还有CSS的代码：
