2018-05-29 14:06:42 更新

卡片是一个灵活的、可扩展的内容窗口。它包含了可选的卡片头和卡片脚、一个大范围的内容、上下文背景色以及强大的显示选项。


创建卡片

我们可以通过 Bootstrap4 的 .card 与 .card-body 类来创建一个简单的卡片,实例如下:

<div class="card">

  <div class="card-body">简单的卡片</div>

</div>


头部和底部

.card-header类用于创建卡片的头部样式, .card-footer 类用于创建卡片的底部样式:

<!DOCTYPE html>

</head>
<body>
<div class="container">
  <h2>卡片头部和底部</h2>
  <div class="card">
    <div class="card-header">头部</div>
    <div class="card-body">内容</div> 
    <div class="card-footer">底部</div>
  </div>
</div>
</body>
</html>


多种颜色卡片

Bootstrap 4 提供了多种卡片的背景颜色类: .bg-primary, .bg-success, .bg-info, .bg-warning, .bg-danger, .bg-secondary, .bg-dark 和 .bg-light。

实例:

标题、文本和链接

我们可以在头部元素上使用 .card-title 类来设置卡片的标题 。 .card-text 类用于设置卡片正文的内容。 .card-link 类用于给链接设置颜色。

实例:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>标题、文本和链接</h2>
  <div class="card">
    <div class="card-body">
      <h4 class="card-title">卡片标题</h4>
      <p class="card-text">卡片内容。</p>
      <a href="#" class="card-link">卡片链接</a>
      <a href="#" class="card-link">卡片链接</a>
    </div>
  </div>
</div>
</body>
</html>


图片卡片

我们可以给 <img> 添加 .card-img-top(图片在文字上方) 或 .card-img-bottom(图片在文字下方 来设置图片卡片:

实例:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>图片卡片</h2>
  <p>图片在头部 (card-img-top):</p>
  <div class="card" style="width:400px">
    <img class="card-img-top" src="https://img.yuanmabao.com/zijie/pic/bootstrap4/1527144620597215.png" alt="Card image" style="width:100%">
    <div class="card-body">
      <h4 class="card-title">bootstrap4</h4>
      <p class="card-text">Some example text some example text. John Doe is an architect and engineer</p>
      <a href="#" class="btn btn-primary">See Profile</a>
    </div>
  </div>
  <br>
  <p>图片在底部(card-img-bottom):</p>
  <div class="card" style="width:400px">
    <div class="card-body">
      <h4 class="card-title">bootstrap4</h4>
      <p class="card-text">Some example text some example text. Jane Doe is an architect and engineer</p>
      <a href="#" class="btn btn-primary">See Profile</a>
    </div>
    <img class="card-img-bottom" src="https://img.yuanmabao.com/zijie/pic/bootstrap4/1527144620597215.png" alt="Card image" style="width:100%">
  </div>
</div>
</body>
</html>

如果图片要设置为背景,可以使用 .card-img-overlay 类:

实例:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap4 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://cdn.bootcss.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank"  rel="external nofollow" target="_blank" >
  <script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/popper.js/1.12.5/umd/popper.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
  <script src="https://cdn.bootcss.com/bootstrap/4.1.0/js/bootstrap.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>
<div class="container">
  <h2>文字覆盖图片</h2>
  <p>如果图片要设置为背景,可以使用 .card-img-overlay 类:</p>
  <div class="card img-fluid" style="width:500px">
    <img class="card-img-top" src="https://img.yuanmabao.com/zijie/pic/bootstrap4/30601.png" alt="Card image" style="width:100%">
    <div class="card-img-overlay">
      <h4 class="card-title">W3Cschool</h4>
      <p class="card-text">Some example text some example text. Some example text some example text. Some example text some example text. Some example text some example text.</p>
      <a href="#" class="btn btn-primary">See Profile</a>
