材质UI响应卡

我正在测试Material-UI。我已经使用Bootstrap很长时间了，但是对将某些React项目适应Material-UI感兴趣。我一直试图弄清楚的是如何在Material-UI中创建响应卡。过去，我非常依赖Bootstraps响应式容器，所以我不明白为什么我的卡会随页面扩展而不会因窗口浓缩而收缩...如果我们打算为该脚本编写自定义CSS这个我很酷，只需要指出正确的方向即可。

问题：

1. Material-UI中的响应卡是不是很重要？

2. 还是我们要编写CSS来使显卡响应？

3. 如果是这样，我在哪里可以学到呢？（过去大量依赖于Bootstrap）

在此先感谢您的帮助！
