这里是链接to the js fiddle

<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

       Aliquam ornare wisi eu metus. In enim a arcu imperdiet malesuada.

   </div>
   <div class="card-footer text-muted">
    This footer should be at the bottom
  </div>
 </div>
</div>

Answer 1

卡片必须全高。 Bootstrap 4具有h-100 ...的height:100%类...

<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片页脚一个 mt-auto 类

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

Answer 3

我个人会从头开始创建自己的页脚，但是可以使用以下方法将其与底部对齐：将以下内容添加到CSS：

.card {
    height: 100vh;
}
