简单的卡片

我们可以通过 Bootstrap5 的 .card 与 .card-body 类来创建一个简单的卡片，卡片可以包含头部、内容、底部以及各种颜色设置，实例如下:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/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"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>简单的卡片</h2>
  <div class="card">
    <div class="card-body">简单的卡片</div>
  </div>
</div>

</body>
</html>

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>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/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"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <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 5 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。

<body>

<div class="container mt-3">

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-body 类用于设置卡片正文的内容。.card-text 类用于设置卡 .card-body 类中的 <p> 标签，如果说最后一行可以移除底部边距。 .card-link 类用于给链接设置颜色。

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/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"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <h2>标题、文本和链接</h2>
  <div class="card">
    <div class="card-body">
      <h4 class="card-title">Card title</h4>
      <p class="card-text">Some example text. Some example text.</p>
      <a href="#" class="card-link">Card link</a>
      <a href="#" class="card-link">Another link</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：

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/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"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <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://atts.w3cschool.cn/attachments/avatar2/avatar_0.jpg" alt="Card image" style="width:100%">
    <div class="card-body">
      <h4 class="card-title">John Doe</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">Jane Doe</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://atts.w3cschool.cn/attachments/avatar2/avatar_0.jpg" 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:

<!DOCTYPE html>
<html>
<head>
  <title>Bootstrap5 实例</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link href="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/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"  rel="external nofollow" target="_blank"  rel="stylesheet">
  <script src="https://cdn.staticfile.org/twitter-bootstrap/5.1.1/js/bootstrap.bundle.min.js" rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow"  rel="external nofollow" ></script>
</head>
<body>

<div class="container mt-3">
  <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://atts.w3cschool.cn/attachments/avatar2/avatar_0.jpg" alt="Card image" style="width:100%">
    <div class="card-img-overlay">
      <h4 class="card-title">John Doe</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>
    </div>
  </div>
</div>

</body>
</html>
