Question

我在2行中有6个固定高度的div标签布局。当我在div周围添加任何边距时，最右边的div被向下推。我该如何应对？

HTML:
<div class="container">
          <div class="row">
            <div class="col-4 frontPageCells">
              hh
            </div>
            <div class="col-4 frontPageCells">
              hh
            </div>
            <div class="col-4 frontPageCells">
              ty
            </div>
          </div>
          <div class="row">
            <div class="col-4 frontPageCells">
              hh
            </div>
            <div class="col-4 frontPageCells">
              hh
            </div>
            <div class="col-4 frontPageCells">
              ty
            </div>
          </div>
        </div>

CSS:
.frontPageCells{
  background-color: white;
  height: 200px; 
  margin: 2px;
}

试图用负填充值来补偿边距，但可以预见的是，它什么也没做

Answer 1

一个简单的技巧是在col-12 div内添加col-4

.frontPageCells {
  background-color: red;
  height: 200px;
  margin-top: 10px;
}

在div之间添加空格会更改列布局
