Question

我在可折叠卡中的物品列表中遇到了问题，这种情况会发生：

​

我想让它看起来像这样

​

​

是否可以按照需要使用Bootstrap的Grid布局或Flex布局？

Answer 1

您只需组成3列，并将这些卡片堆积在每一列上，而不是将每张卡放在它自己的列上：

<div class="row">
    <div class="col-12 col-md-4">
        <div class="card">#1</div>
        <div class="card">#4</div>
    </div>
    <div class="col-12 col-md-4">
        <div class="card">#2</div>
        <div class="card">#5</div>
    </div>
    <div class="col-12 col-md-4">
        <div class="card">#3</div>
    </div>
</div>

您需要创建3列并将行放入其中。

Answer 3

将布局元素与内容元素组合在一起很少是个好主意。把它们分开，一切都好：

<div class="col-12 col-md-4">
  <div class="card">
