Bootstrap4 卡片

2018-05-29 14:35 更新

卡片是一個(gè)靈活的、可擴(kuò)展的內(nèi)容窗口。它包含了可選的卡片頭和卡片腳、一個(gè)大范圍的內(nèi)容、上下文背景色以及強(qiáng)大的顯示選項(xiàng)。

創(chuàng)建卡片

我們可以通過(guò) Bootstrap4 的 .card 與 .card-body 類來(lái)創(chuàng)建一個(gè)簡(jiǎn)單的卡片，實(shí)例如下:

<div class="card">
  <div class="card-body">簡(jiǎn)單的卡片</div>
</div>

頭部和底部

.card-header類用于創(chuàng)建卡片的頭部樣式， .card-footer 類用于創(chuàng)建卡片的底部樣式：

標(biāo)題、文本和鏈接

我們可以在頭部元素上使用 .card-title 類來(lái)設(shè)置卡片的標(biāo)題。 .card-text 類用于設(shè)置卡片正文的內(nèi)容。 .card-link 類用于給鏈接設(shè)置顏色。

圖片卡片

我們可以給 <img> 添加 .card-img-top（圖片在文字上方）或 .card-img-bottom（圖片在文字下方來(lái)設(shè)置圖片卡片：

<body>
<div class="container">
  <h2>圖片卡片</h2>
  <p>圖片在頭部 (card-img-top):</p>
  <div class="card" style="width:400px">
    <img class="card-img-top" src="http://m.hgci.cn/attachments/image/20180524/1527144620597215.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>圖片在底部(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>

如果圖片要設(shè)置為背景，可以使用 .card-img-overlay 類:

  <h2>文字覆蓋圖片</h2>
