Bootstrap卡无法设置样式

标签： html css twitter-bootstrap

我正在编辑一个旧网站。该网站使用bootstrap 3.3.6 

<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>
<div class="col-lg-12">
  <div class="card">
    <div class="card-header">
      Example
    </div>
    <div class="card-body">
      <ul id="example">
      </ul>
    </div>
  </div>
</div>

使用此代码，卡片无法设置样式。引导程序3.3.6不支持此功能吗？如果是，我该如何升级bootstrap？只需更改bootstrap.min.css文件？这会破坏网站的其他部分吗？

Bootstrap v3中没有卡组件，它是v4中的新功能。

Bootstrap v4中有许多重大变化。 请参阅他们的网站以了解更改和Migration Guide

目前，请使用以下代码段来设置您的卡片样式。我从bootstrap 4复制了整个card.css。

自Bootstrap 4开始提供卡片。您可以使用片段，也可以使用＆＃39; well＆＃39;上课以获得理想的效果。如果使用井类，则必须进行一些自定义样式。 链接到井的解释： https://www.w3schools.com/bootstrap/bootstrap_wells.asp
