如何使 Bootstrap 4 卡片在卡片列中的高度相同？

Question

我正在使用 Bootstrap 4 alpha 2 并利用卡片。具体来说，我正在处理从官方文档中获取的 这个示例。如何使所有卡片的高度相同？

我现在能想到的就是设置以下 CSS 规则：

 .card {
    min-height: 200px;
}

但这只是一个硬编码的解决方案，在一般情况下是行不通的。我认为的代码与文档中的代码相同，即：

 <div class="card-columns">
  <div class="card">
    <img class="card-img-top" data-src="..." alt="Card image cap">
    <div class="card-block">
      <h4 class="card-title">Card title that wraps to a new line</h4>
      <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
    </div>
  </div>
  <div class="card card-block">
    <blockquote class="card-blockquote">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
      <footer>
        <small class="text-muted">
          Someone famous in <cite title="Source Title">Source Title</cite>
        </small>
      </footer>
    </blockquote>
  </div>
  <div class="card">
    <img class="card-img-top" data-src="..." alt="Card image cap">
    <div class="card-block">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card card-block card-inverse card-primary text-xs-center">
    <blockquote class="card-blockquote">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat.</p>
      <footer>
        <small>
          Someone famous in <cite title="Source Title">Source Title</cite>
        </small>
      </footer>
    </blockquote>
  </div>
  <div class="card card-block text-xs-center">
    <h4 class="card-title">Card title</h4>
    <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
    <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
  </div>
  <div class="card">
    <img class="card-img" data-src="..." alt="Card image">
  </div>
  <div class="card card-block text-xs-right">
    <blockquote class="card-blockquote">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer posuere erat a ante.</p>
      <footer>
        <small class="text-muted">
          Someone famous in <cite title="Source Title">Source Title</cite>
        </small>
      </footer>
    </blockquote>
  </div>
  <div class="card card-block">
    <h4 class="card-title">Card title</h4>
    <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
    <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
  </div>
</div>

您可以将课程放在“行”或“列”上吗？如果您在行中使用它，则不会在卡片（边框）上可见。 https://getbootstrap.com/docs/4.6/utilities/flex/#align-items

 <div class="container">
    <div class="row">
        <div class="col-lg-4 d-flex align-items-stretch">
            <!--CARD HERE-->
        </div>
        <div class="col-lg-4 d-flex align-items-stretch">
            <!--CARD HERE-->
        </div>
        <div class="col-lg-4 d-flex align-items-stretch">
            <!--CARD HERE-->
        </div>
    </div>
</div>
