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>
</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; 
    }
}

您可以添加d-flex和flex-column的div与卡体。

下面是一个工作示例:

这对我来说很有效:

<div class="card card-body " style="height:80% !important">

强迫我们的CSS在bootstrap一般CSS。

你可以把类放在“行”或“列”? 如果你在一行上使用它，将不会在卡(边界)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>

如果有人感兴趣，有一个jquery插件叫做:jquery. matchheight .js

https://github.com/liabru/jquery-match-height

matchHeight使所有选定元素的高度完全相等。它处理了许多导致类似插件失败的边缘情况。

对于一排卡片，我使用:

<div class="row match-height">

然后在站点范围内启用:

$('.row.match-height').each(function() {
   $(this).find('.card').not('.card .card').matchHeight(); // Not .card .card prevents collapsible cards from taking height
});

以下是我的做法:

CSS:

.my-flex-card > div > div.card {
    height: calc(100% - 15px);
    margin-bottom: 15px;
}

HTML:

<div class="row my-flex-card">
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                aaaa
            </div>
        </div>
    </div>
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                bbbb
            </div>
        </div>
    </div>
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                cccc
            </div>
        </div>
    </div>
    <div class="col-lg-3 col-sm-6">
        <div class="card">
            <div class="card-block">
                dddd
            </div>
        </div>
    </div>
</div>
