Bootstrap4 使卡片标题高度相同

Question

以 Bootstrap 4 的定价模板为例，假设我有不同文本长度的卡片标题，这样在某些屏幕分辨率下卡片标题的高度就会不同。我想确保它们始终具有相同的高度。

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.0.0-beta/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container">
  <div class="card-deck mb-3 text-center">
    <div class="card mb-4 box-shadow">
      <div class="card-header">
        <h4 class="my-0 font-weight-normal">This is a really long header that is going to cause problem.</h4>
      </div>
      <div class="card-body">
        <h1 class="card-title pricing-card-title">$0 <small class="text-muted">/ mo</small></h1>
        <ul class="list-unstyled mt-3 mb-4">
          <li>10 users included</li>
          <li>2 GB of storage</li>
          <li>Email support</li>
          <li>Help center access</li>
        </ul>
        <button type="button" class="btn btn-lg btn-block btn-outline-primary">Sign up for free</button>
      </div>
    </div>
    <div class="card mb-4 box-shadow">
      <div class="card-header">
        <h4 class="my-0 font-weight-normal">Pro</h4>
      </div>
      <div class="card-body">
        <h1 class="card-title pricing-card-title">$15 <small class="text-muted">/ mo</small></h1>
        <ul class="list-unstyled mt-3 mb-4">
          <li>20 users included</li>
          <li>10 GB of storage</li>
          <li>Priority email support</li>
          <li>Help center access</li>
        </ul>
        <button type="button" class="btn btn-lg btn-block btn-primary">Get started</button>
      </div>
    </div>
    <div class="card mb-4 box-shadow">
      <div class="card-header">
        <h4 class="my-0 font-weight-normal">Enterprise</h4>
      </div>
      <div class="card-body">
        <h1 class="card-title pricing-card-title">$29 <small class="text-muted">/ mo</small></h1>
        <ul class="list-unstyled mt-3 mb-4">
          <li>30 users included</li>
          <li>15 GB of storage</li>
          <li>Phone and email support</li>
          <li>Help center access</li>
        </ul>
        <button type="button" class="btn btn-lg btn-block btn-primary">Contact us</button>
      </div>
    </div>
  </div>

我能完成这项工作的唯一方法就是做类似的事情

.card-header{height: 50px;}

在 CSS 中，但这不允许动态调整大小。任何帮助是极大的赞赏。这是Codepen。

在 Bootstrap-4 中，将这些类用于卡片的标题。

1. d-flex - 将其显示更改为flex
2. align-items-center - 垂直居中其内容
3. justify-content-center - 将其内容水平居中
4. h-100 - 让它的高度100%

<div class="container">
  <div class="card-deck mb-3 text-center">
    <div class="card mb-4 box-shadow">
      <div class="card-header d-flex align-items-center justify-content-center h-100">
        <h4 class="my-0 font-weight-normal flex-grow-1">This is a really long header that is going to cause problem. You can add more and more words but height will be the same!

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

        <ul class="list-unstyled mt-3 mb-4">
          <li>10 users included</li>
          <li>2 GB of storage</li>
          <li>Email support</li>
          <li>Help center access</li>
        </ul>

    </div>
    <div class="card mb-4 box-shadow">

      <div class="card-body">

      </div>
    </div>
    </div>
  </div>

更新

如果其中一张卡片的正文内容较少，则其标题的高度较高。将这些类添加到所有卡体以解决此问题。

1. flex-column - 将其flex-direction 更改为列
2. h-100 - 让它的高度100%

<div class="card-body flex-column h-100">

        <h4 class="my-0 font-weight-normal flex-grow-1">This is a really long header that is going to cause problem. You can add more and more words but height will be the same! This is a really long header that is going to cause problem. You can add more and more words but height will be the same!</h4>

只有一种解决方案是使用text-overflow 属性。在引导程序中，您可以使用 .text-truncate 类。它会截断您的标题文本。

您还可以将title 属性赋予您的h1 并为其设置标题文本，以便用户可以在悬停时显示全文

Answer 3

您可以简单地添加 flex 属性来实现这一点。示例如下：

.card-header{
    display: flex;             
    height: 100%;
    align-items: center;
    justify-content: center;

}
  h4{
    flex: 1;
  }

Answer 4

这可能会迟到，但希望对您有所帮助。我有一个类似的问题，我通过添加' '填充符来解决它，以使较短的标题与其他标题的长度相对相同，并且它似乎有效。现在，每个屏幕尺寸的标题高度都相同，尽管我在卡片标题中只使用了“卡片标题”类。

Answer 5

这可能也太晚了，但希望它有所帮助。

$(document).ready(function() {
  var x = 0;
  $(".card-deck .card-header, .card-deck .card-footer").each(function(id, it) {
    if ($(it).height() > x) {
      x = $(it).height();
    }
  }).height(x);
});
