我正在使用Bootstrap卡片，当我为卡片设置最小宽度时，当我减小窗口宽度时卡片重叠，如何确保第三张卡片占据下一行（避免重叠）？

<div class="container" style="margin-top:3em;">
      <div class="card-columns">
        <div class="card" style="min-width: 300px;">
          <img src="images/nasoclearSalineNasalSpray.png" class="card-img-top" style="max-height:500px;"alt="images">
          <div class="card-body">
            <h5 class="card-title">Special title treatment</h5>
            <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
            <a href="#" class="btn btn-primary">Go somewhere</a>
          </div>
        </div>

        <div class="card" style="min-width: 300px;">
          <img src="images/pedialytePowder.png" class="card-img-top" style="max-height:500px;" alt="images">
          <div class="card-body">
            <h5 class="card-title">Special title treatment</h5>
            <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
            <a href="#" class="btn btn-primary">Go somewhere</a>
          </div>
        </div>

        <div class="card" style="min-width: 300px;">
          <img src="images/chericofSuspension.png" class="card-img-top" style="max-height:500px;"alt="images">
          <div class="card-body">
            <h5 class="card-title">Special title treatment</h5>
            <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
            <a href="#" class="btn btn-primary">Go somewhere</a>
          </div>
        </div>
      </div>
    </div>

【问题讨论】：

最好在 div 中使用引导类 col-lg-4 col-md-6 col-sm-12 和类 card 并在其父级上将 card-columns 替换为 row ... 对于您的问题，删除内联 CSS 并尝试这个：.card { max-width:32%; min-width:300px; float:left; margin-right:1%; } .card-columns { display:block; column-count:inherit; border:1px dotted red }
为什么不在引导列中使用卡，例如 col-sm-6
实现这一点的一种方法是使用 flex-wrap: wrap;并设置最大宽度，
@AkberIqbal，由于我使用 Handlebars 生成模板，因此我不能将行用作父项，将列用作子项。

<div class="container" style="margin-top:3em;">
  <div class="card-columns custom-columns">
    <div class="card">
      <img src="images/nasoclearSalineNasalSpray.png" class="card-img-top" style="max-height:500px;"alt="images">
      <div class="card-body">
        <h5 class="card-title">Special title treatment</h5>
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>

    <div class="card">
      <img src="images/pedialytePowder.png" class="card-img-top" style="max-height:500px;" alt="images">
      <div class="card-body">
        <h5 class="card-title">Special title treatment</h5>
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>

    <div class="card">
      <img src="images/chericofSuspension.png" class="card-img-top" style="max-height:500px;"alt="images">
      <div class="card-body">
        <h5 class="card-title">Special title treatment</h5>
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>
  </div>
</div>

移除宽度 min-width:300px;

添加了 .custom-columns

    @media (max-width: 700px) {
        .card-columns.custom-columns {
            column-count: 1;
        }
    }
    @media (min-width: 700px) {
        .card-columns.custom-columns {
            column-count: 2;
        }
    }
    @media (min-width: 1000px) {
        .card-columns.custom-columns {
            column-count: 3;
        }
    }
    @media (min-width: 1400px) {
        .card-columns.custom-columns {
            column-count: 4;
        }
    }

如果您使用引导程序，则使用 i 的网格系统。

我更喜欢你的回答：你尊重 de Bootstrap 精神。一切都是在 Bootstrap 中解决这个问题的，所以不需要额外的代码。
