小试牛刀1：制作一个简单的导航栏页面_html/css_WEB-ITnose
页面效果大概目标：http://www.daxues.cn/forum.php
一、布局
从页面来看，可以分为三个部分，第一部分是导航栏，第二部分是有“大学生论坛”字样的蓝色部分，余下的是第三部分也可以分为二部分：搜索栏和主要内容区域；而主要内容区域又可分为：导航栏、主体、底部。
1 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 2 <html xmlns="http://www.w3.org/1999/xhtml"> 3 <head> 4 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 5 <title>大学生论坛</title> 6 <style type="text/css"> 7 *{margin:0;padding:0;} 8 body{ 9 margin:0; 10 width:100%;11 height:1000px; 12 }13 .header-nav{width:80%;margin:0 auto;height:50px;}14 .section{15 width:100%;16 height:100px;17 background-color:#726FEA;18 }19 .main{width:100%;height:850px;background-color:#D5F5FB;}20 .main-header{width:80%;height:100px;margin:0 auto;}21 .container{width:80%;height:750px;margin:0 auto;}22 .main-nav{height:100px;}23 .content{height:600px;}24 .footer{height:50px;}25 </style>26 </head>27 28 <body>29 <div class="header-nav"></div>30 <div class="section"></div>31 <div class="main">32 <div class="main-header"></div>33 <div class="container">34 <div class="main-nav"></div>35 <div class="content"></div>36 <div class="footer"></div>37 </div>38 </div>39 </body>40 </html>大概效果如下：
（下面还有一个底部，这里没有显示出来）
二、现在开始设计第一、二两大部分
第一部分主要是导航等，第二部分就是图片和文字。第三部分就是表单、导航等。

难点在于第一部分的所有内容要求在同一水平线上，实例中我是运用float、margin和padding来实现的，但是这种方法有一个弊端，它只适用于我的电脑，如果换一台比较大或者比较小的电脑，每个部分的排序可能会打乱。
（技术不是很好，只做出了一个大概的模板~大家有更好的建议可以提出来！o(╯□╰)o）
