具有视口列数的Bootstrap 4卡座

Question

我正在尝试在引导程序4中实现卡片组功能，以使我所有的卡片都具有相同的高度。

引导程序提供的示例显示了4张漂亮的卡片，但是无论视口如何，它都是4张卡片。

这对我来说没有意义，因为我认为您希望缩小卡的最小尺寸，以使内容看起来仍然不错。

然后，我尝试添加一些视口类以打破屏幕尺寸，但是一旦添加了该div，卡片组将不再适用，因此不会使卡片的高度相等。

我怎样才能做到这一点？这是缺少的功能，将在完整版的Bootstrap 4中解决吗？

如果您想要一个响应式卡片组，请使用可见性实用程序来强制将每X列换行到不同的视口宽度（断点）…

[Bootstrap 4响应 式卡座]（v 4.1 ）

Bootstrap 4 alpha 2的原始答案：

您可以 使用网格col-*-*来获取不同的宽度（而不是卡片甲板），然后使用flexbox将等高设置为cols。

.row > div[class*='col-'] {
  display: flex;
  flex:1 0 auto;
}

问题在于，没有Flexbox的情况下，很难控制宽度的card-deck用途table-cell。从Bootstrap 4 Alpha
6开始，flexbox是默认的，因此flexbox不需要其他CSS，并且 h-100
该类可用于使卡全高
