这是js小提琴的链接

<div class="container">
   <div class="card text-center">
     <div class="card-header">Featured</div>
     <div class="card-body">
       <h5 class="card-title">Special title treatment</h5>
       <p class="card-text">This text should be equi-distance from header 
       and footer. </p>
       <p class="card-text">
       Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Nullam 
       sapien sem, ornare ac, nonummy non, lobortis a enim. Nam sed 
       tellus id magna elementum tincidunt. Pellentesque habitant morbi 
       tristique senectus et netus et malesuada fames ac turpis egestas. 
       Aliquam ornare wisi eu metus. In enim a arcu imperdiet malesuada. 
       Nam quis nulla. Vivamus luctus egestas leo. 
       </p>
   </div>
   <div class="card-footer text-muted">
    This footer should be at the bottom
  </div>
 </div>
</div>

Answer 1

该卡需要全高。Bootstrap 4 有一个h-100类height:100%...

<div class="container h-100">
<div class="card h-100 text-center">
  <div class="card-header">
    Featured
  </div>
  <div class="card-body">
    <h5 class="card-title">Special title treatment</h5>
    ...
  </div>
  <div class="card-footer text-muted">
    This footer should be at the bottom
  </div>
</div>
</div>

我认为最简单的方法是给卡页脚一个 mt-auto 类

  <div class="card-footer mt-auto" >
    Whatever
  </div>
