Question

我正在使用Bootstrap 4 alpha 2并利用卡片。具体来说，我正在使用来自官方文档的this example。正如标题所说，我怎样才能让所有卡片都高度相同？

编辑：我现在想的就是设置以下CSS规则：

<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>

但这只是一个硬编码的解决方案，在一般情况下不会起作用。我视图中的代码与文档中的代码相同，即：

{{1}}

Answer 1

您可以将这些课程放在＆＃34;行＆＃34;或者＆＃34;栏＆＃34;？如果你在行上使用它，就不会在卡片（边框）上看到它们。 https://v4-alpha.getbootstrap.com/utilities/flexbox/#align-items

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

这里的其他一些答案看起来很古怪＆＃39;为什么要使用最小高度甚至更糟的固定高度？

我认为这个问题（相等的高度）是离开浮动障碍div的原因的一部分？

Answer 2

我正在使用Bootstrap 4（Beta 2）。与此同时，情况似乎发生了变化。我有同样的问题，并找到了一个简单的解决方案。这是我的代码：

<div class="container-fluid content-row">
    <div class="row">
        <div class="col-sm-12 col-lg-6">
            <div class="card h-100">
                … content card …
            </div>
        </div>
        … all the other cards … 
    </div>
</div>

使用“col-sm-12 col-lg-6”我已经让卡片响应了。使用“card h-100”，我将所有卡设置为其父列的高度。在我的系统上这是有效的，但我不是专业人士。所以，希望我能帮助别人。

Answer 3

最佳解决方案，Bootstrap 4可满足您的所有需求：使用.d-flex和.flex-fill课程。不要使用card-decks，因为他们没有回应。我使用了col-sm，您可以使用所需的.col课程。

这是野兽，尝试将浏览器窗口缩小为XS以查看它的实际效果：

Answer 4

更新：在 Bootstrap 4 中，flexbox现在是默认行，每行card-deck行将包含3张卡片。卡片将填满整个高度。

http://www.codeply.com/go/x91w5Cl6ip

Bootstrap 4 alpha card-columns使用的CSS3列实际上并不支持相同的高度（除了仅在Firefox中支持的列填充）。

如果你改为启用Bootstrap 4 flexbox模式，你可以使用card-deck和一点CSS来均衡高度并包装每3列。

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

Bootstrap Card of same Height in Col

Answer 5

我是这样做的：

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>

Answer 6

您可以使用卡座，它将对齐所有卡...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>

Answer 7

您可以应用h-100类，它代表高度100％。

Answer 8

另一种有用的方法是Card Grids：

<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>

Answer 9

将卡片包裹在

中

<div class="card-group"></div>

或

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

Answer 10

我采取了略微不同的方法。使用Card Deck wrapper

我添加了一个限制卡块高度的样式规则：

.card .card-block {max-height:300px;overflow:auto;}

这给出了以下结果：

Answer 11

这可能对你有帮助

只需按照此代码

<div class="row">
   <div class="col-md-4 h-100">contents....</div>
   <div class="col-md-4 h-100">contents....</div>
   <div class="col-md-4 h-100">contents....</div>
</div>

使用引导类“h-100”

Answer 12

我是新手，因此，如果我一起缺少任何东西，请原谅。

我尝试了许多上述方法。如果将高度设置为100％，则卡将始终扩展到最长卡的最大长度。容器将约束所有相同的长度。

我想看一下容器，所以我用背景色来帮助我看看发生了什么。

<div class="col-lg-3"  style="background-color: rosybrown;">
    <div class="card w-100" Style="height: 100%">
        <div class="card-body">
            <img src="images/beHappy.png" alt="" class="img-fluid rounded-circle w-25 mb-3">
            <h4>CBe Happy</h2>

Answer 13

您可以使用 d-flex and flex-column 将 card-body 添加到 div。

Hetre 是一个工作示例：

Answer 14

对于 Bootstrap 5 和 4

HEIGHT-将所有卡片放入 div 中，class="card-deck"

WIDTH - 给你所有的卡片样式 {min-width: 50ch}

Answer 15

根据问题我有一个答案，它可能对您有所帮助，您可以使用它。您可以使用 height 属性并将其设置为 height: 100vh; 我已经使用了 70vh 并且卡片将是您提供的固定高度。

Answer 16

实现此（我知道）的最简单方法：

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

在卡的标题和/或其他文本中添加.text-truncate。这将文本强制为一行。使卡片具有相同的高度。

Answer 17

我遇到了这个问题，大多数人使用jQuery ...这是我的解决方案。 “别介意，我只是这个领域的初学者...”

if currentColor === "#fafafa"

.cards-collection {
    .card-item { 
        width: 100%;
        margin: 20px 20px;
        padding:0 ;
        .card {
            border-radius: 10px;
                button {
                    border: inherit;
                }
        }

如果任何卡项目高度为400px（基于其内容），因为flex-align的默认设置为Stretch，则.card-item（row或card-collection类的子级）将被拉伸。使得卡的高度为父代的100％将会占据此全高。

我希望我是正确的。是吗？

如果有人有兴趣，有一个名为jquery.matchHeight.js的jquery插件

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

matchHeight使所有选定元素的高度完全相等。它处理许多边缘情况，导致类似的插件失败。

对于一排牌，我使用：

<div class="row match-height">

然后在网站范围内启用：

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

只需使用CSS添加所需的高度，例如：

.card{
    height: 350px;
}

您必须添加自己的CSS。

如果你查看文档，这是针对 Masonry 样式的 - 那就是它们的高度不同。

这对我来说很好：

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

在引导程序常规CSS上强制使用我们的CSS。
