css - 引导程序上的偏移量和边距

问题描述

我在 bootstrap 4 上玩偏移量和边距，我想实现像这张图片一样的东西，除了盒子之间的空白之外，一切都在工作，当你去中等大小时，蓝色和黄色的盒子彼此相邻但是当我把 mr- md-2 然后蓝框掉了，为什么？我想要所有盒子和尺寸之间的空白，如图所示在此处输入图像描述

解决方案

col考虑到在 BS Grid 系统中， umns 之间（或s之间）没有边距，row但存在排水沟：

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;
}
