如何使Bootstrap 4卡在卡列相同的高度?

我使用引导4 alpha 2和利用卡。具体来说，我正在处理这个来自官方文档的例子。我怎样才能使所有的卡片都是相同的高度?

我现在能想到的就是设置下面的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。在我的视图中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>

你可以使用card-deck，它会对齐所有的卡片…这来自bootstrap 4官方页面。

<div class="card-deck">
  <div class="card">
    <img class="card-img-top" src="..." alt="Card image cap">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <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>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <img class="card-img-top" src="..." alt="Card image cap">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <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">
    <img class="card-img-top" src="..." alt="Card image cap">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <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>
</div>

更新:在Bootstrap 4中，flexbox现在是默认的，每个卡组行将包含3张卡。卡片将填满高度。

Bootstrap 4 alpha卡片列使用CSS3列，它并不真正支持等高(列填充除外，它只在Firefox中支持)。

如果你启用Bootstrap 4 flexbox模式，你可以使用卡片组和一点CSS来平衡高度，每3列换行一次。

@media (min-width:34em) {
    .card-deck > .card
    {
        width: 29%;
        flex-wrap: wrap;
        flex: initial; 
    }
}

另一个有用的方法是卡片网格:

<div class="row row-cols-1 row-cols-md-2"> <div class="col mb-4"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <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> <div class="col mb-4"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <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> <div class="col mb-4"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content.</p> </div> </div> </div> <div class="col mb-4"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <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> </div>

实现这一目标的最简单方法(我所知道的):

将.text monospace应用于卡片中的所有文本。将卡片中的所有文本限制为相同数量的字符。

更新

在卡片的标题和或其他文本中添加.text-truncate。这将迫使文本变成一行。使卡片具有相同的高度。

把卡片包在里面

< div级= card-group " > < / div >

< div级= card-deck " > < / div >

你可以应用h-100级别，代表高度100%。
