老师批语：中间内容区的展现形式有多种的
一、双飞翼布局与圣杯布局的共同点和区别
圣杯布局和双飞翼布局基本上是一致的，都是两边固定宽度，中间自适应的三栏布局，其中，中间栏放到文档流前面，保证先行渲染。
这两种布局解决方案大体相同，都是三栏全部float:left浮动，区别在于解决中间栏div的内容不被遮挡上，圣杯布局是为中间内容区域添加box-sizing: border-box属性从而使中央内容区总大小不受padding影响，使两侧内容布局在中央内容两侧的padding上。
双飞翼布局是使用宽度分离方法，在中间栏的div中嵌套一个div，内容写里面的div里，然后对嵌套的div设置尺寸，里面的div设置padding值，效果上表现为两侧布局在里面div的padding上面。
