我正在尝试在引导程序 4 中实现卡片组功能，以使我所有的卡片都具有相同的高度。

bootstrap 提供的示例显示了 4 张不错的卡片，但无论视口如何，它都是一行中的 4 张卡片。请参阅此处的代码。

这对我来说没有意义，因为我假设您希望卡片缩小到最小尺寸，以便您的内容仍然看起来不错。

然后我尝试添加一些视口类来打破屏幕尺寸，但是一旦添加了该 div，卡片组就不再适用，因此不会使卡片高度相等。

我怎样才能做到这一点？这是将在 Bootstrap 4 的完整版本中解决的缺失功能吗？

这是小提琴：https ://jsfiddle.net/crrm5q9m/

如果您想要一个响应式卡片组，请使用可见性实用程序强制在不同视口宽度（断点）上的每 X 列换行...

Bootstrap 4 响应式卡片组（v 4.1）

Bootstrap 4 alpha 2 的原始答案：

您可以使用网格col-*-*来获取不同的宽度（而不是卡片组），然后使用 flexbox 为 cols 设置相等的高度。

.row > div[class*='col-'] {
  display: flex;
  flex:1 0 auto;
}

http://codeply.com/go/O0KdSG2YX2（阿尔法 2）

问题是没有 flexbox 启用了难以控制宽度的card-deck用途。table-cell自 Bootstrap 4 Alpha 6 起，flexbox 是默认的，因此 flexbox 不需要额外的 CSS，并且h-100该类可用于使卡片全高： http: //www.codeply.com/go/gnOzxd4Spk

这是 Sass 的解决方案，可根据断点配置每行的卡数：https ://codepen.io/migli/pen/OQVRMw

它适用于 Bootstrap 4 beta 3

// Bootstrap 4 breakpoints & gutter
$grid-breakpoints: (
    xs: 0,
    sm: 576px,
    md: 768px,
    lg: 992px,
    xl: 1200px
) !default;

$grid-gutter-width: 30px !default;

// number of cards per line for each breakpoint
$cards-per-line: (
    xs: 1,
    sm: 2,
    md: 3,
    lg: 4,
    xl: 5
);

@each $name, $breakpoint in $grid-breakpoints {
    @media (min-width: $breakpoint) {
        .card-deck .card {
            flex: 0 0 calc(#{100/map-get($cards-per-line, $name)}% - #{$grid-gutter-width});
        }
    }
}

我研究了另一个使用水平列表组 + flex 实用程序而不是卡片组的解决方案：

https://codepen.io/migli/pen/gOOmYLb

将任何类型的元素组织到响应式网格中是一种简单的解决方案

<div class="container">
    <ul class="list-group list-group-horizontal align-items-stretch flex-wrap">
        <li class="list-group-item">Cras justo odio</li>
        <li class="list-group-item">Dapibus ac facilisis in</li>
        <li class="list-group-item">Morbi leo risus</li>
        <li class="list-group-item">Cras justo odio</li>
        <li class="list-group-item">Dapibus ac facilisis in</li>
        <!--= add as many items as you need  =-->
    </ul>
</div>

.list-group-item {
    width: 95%;
    margin: 1% !important;
}

@media (min-width: 576px) {
    .list-group-item {
        width: 47%;
        margin: 5px 1.5% !important;
    }
}

@media (min-width: 768px) {
    .list-group-item {
        width: 31.333%;
        margin: 5px 1% !important;
    }
}

@media (min-width: 992px) {
    .list-group-item {
        width: 23%;
        margin: 5px 1% !important;
    }
}

@media (min-width: 1200px) {

        margin: 5px .5% !important;
    }

我通过min-width在卡片上添加一个来实现这一点：

<div class="card mb-3" style="min-width: 18rem;">
  <p>Card content</p>
</div>

卡片不会低于此宽度，但仍能正确填充每一行并具有相等的高度。

我已经使用 CSS Grid 来解决这个问题。CSS Grid 将使所有元素在同一行，高度相同。

不过，我还没有考虑让所有行中的所有元素都具有相同的高度。

无论如何，这是如何做到的：

HTML：

<div class="grid-container">

  <div class="card">...</div>
  <div class="card">...</div>
</div>

CSS：

.grid-container {
  display: grid;  
  grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
}

这是一个完整的 JSFiddle。 https://jsfiddle.net/bluegrounds/owjvhstq/4/

我创建了 4 张卡片并将此代码放在第二张和第三张卡片之间，试试这个。

这个答案适用于那些使用 Bootstrap 4.1+ 的人以及那些关心 IE 11 的人

Card-deck 不会根据视口大小调整可见的卡片数量。

以上方法有效，但不支持 IE。通过以下方法，您可以实现类似的功能和响应卡。

您可以管理在不同断点中显示/隐藏的卡片数量。

在 Bootstrap 4.1+ 中，默认列的高度相同，只需确保您的卡片/内容使用所有可用空间。运行代码段，你就会明白

根据视口按最小宽度定义列：


    /* Number of Cards by Row based on Viewport */
    @media (min-width: 576px) {
        .card-deck .card {
            min-width: 50.1%; /* 1 Column */
            margin-bottom: 12px;
        }
    }

    @media (min-width: 768px) {
        .card-deck .card {
            min-width: 33.4%;  /* 2 Columns */
        }
    }

    @media (min-width: 992px) {
        .card-deck .card {
            min-width: 25.1%;  /* 3 Columns */
        }
    }

    @media (min-width: 1200px) {
        .card-deck .card {
            min-width: 20.1%;  /* 4 Columns */

使用 Bootstrap 4.4.1，我能够通过添加一些 scss 来使用简单的类来设置每副牌的数量。

HTML

<div class="card-deck deck-1 deck-md-2 deck-lg-3">
   <div class="card">
      <h2 class="card-header">Card 1</h3>
      <div class="card-body">
          Card body
      </div>
      <div class="card-footer">
          Card footer
      </div>
   </div>
   <div class="card">
      <h2 class="card-header">Card 2</h3>
      <div class="card-body">
          Card body
      </div>
      <div class="card-footer">
          Card footer
      </div>
   </div>
   <div class="card">
      <h2 class="card-header">Card 3</h3>
      <div class="card-body">
          Card body
      </div>
      <div class="card-footer">
          Card footer
      </div>
   </div>
</div>

@Zim 在上面提供了一个很好的解决方案（我当之无愧的投票），但是，它并不完全符合我的需要，因为我在 Jekyll 中实现了这个，并且希望我的卡片组在我每次添加帖子时自动更新我的网站。在 Jekyll 中，随着每个新帖子发展出这样的卡片组是直截了当的，挑战在于正确放置断点。我的解决方案利用了额外的液体标签和模数学。

虽然这个问题很老，但我发现它并发现它很有用，也许有一天有人会想用 Jekyll 来做这个。

<div class = "container">
  <div class = "card-deck">

    {% for post in site.posts %}
      <div class = "card border-0 mt-2">
        <a href = "{{ post.url }}"><img src = "{{ site.baseurl }}{{ post.image }}" class = "mx-auto" alt = "..."></a>
        <div class = "card-body">
          <h5 class = "card-title"><a href = "{{ post.url }}">{{ post.title }}</a></h5>
          <span>Published: {{ post.date | date_to_long_string }} </span>
          <p class = "text-muted">{{ post.excerpt }}</p>
        </div>
        <div class = "card-footer bg-white border-0"><a href = "{{ post.url }}" class = "btn btn-primary">Read more</a></div>
      </div>

      <!-- Use modulo to add divs to handle break points -->
      {% assign sm = forloop.index | modulo: 2 %}
      {% assign md = forloop.index | modulo: 3 %}
      {% assign lg = forloop.index | modulo: 4 %}
      {% assign xl = forloop.index | modulo: 5 %}

      {% if sm == 0 %}
        <div class="w-100 d-none d-sm-block d-md-none"><!-- wrap every 2 on sm--></div>
      {% endif %}

      {% if md == 0 %}
        <div class="w-100 d-none d-md-block d-lg-none"><!-- wrap every 3 on md--></div>
      {% endif %}

      {% if lg == 0 %}
        <div class="w-100 d-none d-lg-block d-xl-none"><!-- wrap every 4 on lg--></div>
      {% endif %}

      {% if xl == 0 %}
        <div class="w-100 d-none d-xl-block"><!-- wrap every 5 on xl--></div>
      {% endif %}

    {% endfor %}
  </div>
</div>

整个代码块可以直接在网站中使用，也可以保存在 Jekyll 项目_includes文件夹中。

有一个更简单的解决方案 -设置卡片元素的固定高度- 标题和正文。这样，我们可以使用标准的 boostrap 列网格设置响应式布局。

这是我的例子： http ://codeply.com/go/RHDawRSBol

 <div class="card-deck text-center">
    <div class="col-sm-6 col-md-4 col-lg-3">
        <div class="card mb-4">
            <img class="card-img-top img-fluid" src="//placehold.it/500x280" alt="Card image cap">
            <div class="card-body" style="height: 20rem">
                <h4 class="card-title">1 Card title</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>
                <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
            </div>
        </div>

我花了一点时间才弄清楚这一点，但答案是不要使用卡片组，而是使用.rowand .cols。

这会生成一组响应式卡片，其中包含每个屏幕尺寸的详细信息：3 张卡片用于xl， 2 张用于lgand md， 1 张用于smand xs。 .my-3在顶部和底部放置填充物，使它们看起来不错。

mixin postList(stuff)
  .row
    - site.posts.each(function(post, index){
      .col-sm-12.col-md-6.col-lg-6.col-xl-4
        .card.my-3
          img.card-img-top(src="...",  alt="Card image cap")
          .card-body
            h5.card-title Card title #{index}
            p.card-text Some quick example text to build on the card title and make up the bulk of the cards content.
            a.btn.btn-primary(href="#") Go somewhere
    - })
