css - 如何在固定大小的多行上使用带有 Bootstrap 4 的卡片？

标签 css twitter-bootstrap bootstrap-4

目标:

  • 所有卡片的高度 (128px) 和宽度 (128px) 相同
  • 如果有很多卡片 并且屏幕不够宽，在第二行显示卡片。

我使用的是 Bootstrap 4，目前，我的卡片只有一行。我阅读了文档并尝试了很多代码。目前，我不明白为什么我的卡片太小并且不符合 128px 的大小。 结果与网格系统响应相同。

最佳答案

从card-deck 中取出您的卡片并将它们放在行 中。如果您想将整个内容水平居中，请将 justify-content-center 类添加到行中(单击“运行代码按钮”并展开至整页):

请注意，我还为间距添加了类 mx-2 mb-3。
