Bootstrap Grid-为什么我的专栏只在小屏幕上重叠？

时间：2019-04-06 20:53:23

标签： html css bootstrap-4

Bootstrap 4.1

我正在尝试创建一个仪表板。当我将浏览器的尺寸缩小到较小的视图时，我希望div可以彼此叠放，但是它们却不能叠放。我尝试更改<div class="container">位置，但这似乎并没有改变

如果您运行代码段，我认为它将显示它们堆叠但重叠-否则，这是重叠的屏幕截图：Overlapping IMGUR

这是大中型的样子：Not Overlapping IMGUR

与高度有关吗？看起来好像不尊重较大屏幕宽度时的100px高度。

使用min-height: 100px代替height: 100px。当列堆叠在较小的屏幕上时，这将使您的行增长到100px以上。

购买将行设置为height: 100px时，您将限制它们在列堆叠时增长，并且行在堆叠时需要增长100px以上，以避免重叠。
