如何使嵌套的flexbox工作
高度100%在flexbox列子上
如何使flexbox子项100%的父级高度？
我需要一个响应的整页,如下图所示:
使用页眉和页脚以及中间5列在剩余空间中均匀填充高度,然后当我进行媒体查询时,填写移动设备的屏幕,如下所示:
这是我到目前为止的代码......

</div>除了Michael Coker的回答,如果你一直使用Flexbox,你可以大大减少你的标记和CSS,并获得这个惊人的结果.
我还包括您评论/询问的背景图片和媒体查询,以表明这是多么简单.
在CSS中做了一些笔记.当涉及到页眉和页脚时,你可以根据需要给它们一个高度,但这不需要它,所以我把它们排除在外以便人们可以看到Flexbox如何在分发内容方面表现出色...希望我有这项技术20年前:)
