html – 将弹性项目固定到容器的底部

我有4个块,标题,描述和按钮.

我希望将标题和描述保持在顶部,并且无论描述或标题有多长,按钮都要在底部对齐.

我还需要保持相同的HTML结构.

我实际需要的示例图片：

有人可以弄清楚吗？到目前为止,我还没有在互联网上找到解决办法.

解决方法

由于您正在使用行方向Flex容器,因此无法将最后一项固定到底部.你正在处理横轴空间分布,这意味着柔性线被拉伸或打包,并且没有办法将两个项目固定到顶部和一个到底部(除非你超越flexBox并使用绝对定位).

这是一个完整的解释.

使布局工作的一种简单有效的方法是列方向容器,在最后一项上具有弹性自动边距.通过在主轴上对齐项目,您可以将各个项目分开.

以下是flex auto margin的解释：
