我正在尝试创建一个投资组合网站，希望在轮播上有一个部分，以2x2网格显示我已完成的项目。我会将每个项目放入卡中，并且当屏幕尺寸太小时，网格将变成1x4，将每个项目卡显示在自己的行上。
我花了很多时间浏览Bootstrap文档以及一些youtube教程。虽然我可以在台式机屏幕尺寸上寻找卡片大小，但将其拆散并转移到移动设备时看起来糟透了。我尝试使用可以与“ col”类相关联的各种属性，但是在我目前的情况下，它们似乎没有任何帮助。我遇到了一些障碍，不知道还有哪些其他资源可以帮助我解决此问题。

您可以使用col-sm-6引导类使用make 4x4网格，它将在sm（如果需要，则为{xs）的屏幕尺寸下将其转换为1x4移动尺寸。
