针对五个模块的不同类型布局demo，基本上概括了所有需求，很有代表性。注意dtd为strict模式，编码是已改为utf。
个人觉得虽然实用有限，但作为技术参考，一定程度上总结了很多解决方案。
固定代码架构，分为五个部分 eader, content, navigation, other stuff and footer
HTML 代码:
<div id="container">
<div id="header">Header</div>
<div id="wrapper">
<div id="content">Content</div>
</div>
<div id="navigation">Navigation</div>
<div id="extra">Extra stuff</div>
<div id="footer">Footer</div>
</div>
