对于这样的布局，我强烈建议使用Grid 960系统:

http://960.gs/ [ ^ ]

这将使您可以在固定宽度的容器中创建三列-您还可以使用此布局系统创建页眉和页脚.

这是一种非常好的方法-经常使用，因此可以在需要时获得支持，并且非常容易设置.

以下页面更详细地介绍了实际使用960g的方法-包括如何处理标头:

For layouts such as this, I would strongly recommend using the Grid 960 system:

http://960.gs/[^]

This will let you create three columns in a fixed width container - you can also create the header and footer with this layout system.

This is a very good approach - it is commonly used so you can get support if you need it and very easy to set up.
