Question

我在bootstrap 4上玩偏移和边距，我想实现像这张照片之类的东西除了盒子之间的白色空间外什么都有用，当你去中等尺寸时，蓝色和黄色的盒子彼此相邻但是当我把mr-md-2然后蓝盒子掉下来，为什么呢？我希望所有方框和尺寸之间都有空格，如图

考虑到在BS网格系统中，col umns之间（或者row之间没有边距）但是有排水沟：

全屏运行此代码段并调整窗口大小：

.row > div {
  /* background-color: lightsteelblue; */
  margin-top:20px;
}

.content {
  background-color: burlywood;
  height: 200px;
}
