Bootstrap 4：卡片作为具有相同高度和宽度的网格答案

【问题标题】：Bootstrap 4: cards as grid with the same height and widthBootstrap 4：卡片作为具有相同高度和宽度的网格
【发布时间】：2018-07-16 07:49:07
【问题描述】：

我正在尝试在具有相同高度和宽度的网格中订购卡片。这些卡片将具有不同大小的不同内容。他们也应该在每行中增加 3 个。每行可以有不同的高度，但行内的高度应该相同。每张卡片的宽度对于整个网格应该是相同的。

<div class="container">
  <div class="row align-items-stretch justify-content-start card-deck">
   <div class="card">
     <div class="card-body">
      <div class="card-text">
        Card 1
      </div>
     </div>
   </div>
   <div class="card">
     <div class="card-body">
      <div class="card-text">
        Card 1 sasddddddddddddddddd asdd as dassssssssssssssssssssssssss
      </div>
     </div>
   </div>
   <div class="card">
     <div class="card-body">
      <div class="card-text">
        Card 1
      </div>
     </div>
   </div>
   <div class="w-100">

   </div>
   <div class="card">
     <div class="card-body">
      <div class="card-text">
        Card 1

   <div class="card">
     <div class="card-body">
      <div class="card-text">

      </div>
     </div>
   </div>
  </div>
</div>

小提琴：https://jsfiddle.net/q9gp76kL/

我希望收到的结果布局：

我发现当前小提琴存在问题：

行之间没有空格
每行卡片的宽度不同

所以card-deck 似乎不足以解决问题。有什么简单的方法吗？

标签： html css twitter-bootstrap bootstrap-4

【解决方案1】：

您可以简单地定义卡片的宽度（在下面的示例中为style="width: 18rem;"），然后对列使用col-auto 类加上类似mb-3（margin-bottom 3 个单位）的内容作为边距底端。而已。

如果您想将它们整齐地居中对齐，您可以将justify-content-center 添加到行中。或者，如果您更喜欢 justify-content-between 课程，也可以试试。

【讨论】：

不幸的是，这不会使卡片的高度相同。尝试改变卡片的一些内容——在里面放几个<br/>。你会看到有他们的卡比邻居高。
