无法让容器根据其内容进行扩展

Question

我确实尝试了一些我在网上找到的建议，但其中 none 行得通。我尝试 fix the footer at the bottom using Flexbox layout but it didn't work, when I add more cards they overflow and go past the footer. I also followed this answer 并将这两个属性添加到我的主页，但问题是 card-container 没有扩展以适应内容（它显示必须 flex）并且只有主 div（对于整个页面）。

您对这个问题有什么建议或解决方法吗？
