Question

我想知道，如果我希望页眉的紫色和页脚的蓝色在页面上延伸100％，但保持中间的内容与中间的橙色对齐，我该怎么办？实现它？

我是否必须在页眉和页脚周围添加额外的100％div并在其中着色？这似乎是一种废话的方式。

这是我正在使用的代码： http://jsfiddle.net/HMsKa/21/

你可以这样做：My Fiddle

怎么做：

从包装器div中取出页眉和页脚，并为页眉和页脚提供100％的宽度。

要将页眉和页脚的内容放在中心，您需要将页眉和页脚中的内容包装在包装器div中，为其width 600px;并使用margin: auto;将它带入你的页面流程

我是否必须添加额外的div来实现这一目标？
