引导程序+ django，包装卡

Question

我有一个简短的问题。

我将遍历数据库记录，并为每条记录打印一张卡。问题是，如果我不能为每张卡设置新的行，我最终将在两行纸牌之间出现这种可怕的压缩布局

我该如何遍历，为每张卡片制作一张卡片，并且看起来仍然不错？

谢谢！

<div class="row">

<div class="col-4"> 
<div class="card" style="width: 18rem;">
  <div class="card-body">
    <h5 class="card-title">Card title</h5>
    <h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
    <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
    <a href="#" class="card-link">Card link</a>

只需使用间距工具即可。例如：

<div class="col-4 py-3"> 
  <div class="card" style="width: 18rem;">
  ...
  </div>
</div>
