使列高填充行引导程序4

Question

我的页面上有一行包含一些列。这些包含卡片，内容数量略有不同。但我希望这些都是相同的高度。

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<div class="row mx-2 d-flex align-content-stretch flex-wrap flex-grow-1">
  <div class="col-md-3 ">
    <div class="card">
      <img src="image1.jpg" class="img-fluid" alt="" />
      <div class="card-body overflow-hidden text-center">
        <h4 class="color-primary">card 1</h4>
        <p></p>
        <a href="" class="btn btn-info"><i class="zmdi zmdi- 
       download"></i>download</a>
      </div>
    </div>
  </div>
  <div class="col-md-3 ">
    <div class="card">
      <img src="image1.jpg" class="img-fluid" alt="" />
      <div class="card-body overflow-hidden text-center">
        <h4 class="color-primary">card 1</h4>
        <p></p>
        <a href="" class="btn btn-info"><i class="zmdi zmdi- 
           download"></i>download</a>
      </div>
    </div>
  </div>
  <div class="col-md-3 ">
    <div class="card">
      <img src="image1.jpg" class="img-fluid" alt="" />
      <div class="card-body overflow-hidden text-center">
        <h4 class="color-primary">card 1</h4>
        <p></p>
        <a href="" class="btn btn-info"><i class="zmdi zmdi- 
       download"></i>download</a>
      </div>
    </div>
  </div>
  <div class="col-md-3 ">
    <div class="card">
      <img src="image1.jpg" class="img-fluid" alt="" />
      <div class="card-body overflow-hidden text-center">
        <h4 class="color-primary">card 1</h4>
        <p></p>
        <a href="" class="btn btn-info"><i class="zmdi zmdi- 
            download"></i>download</a>
      </div>
    </div>
  </div>
</div>

如您所见，我已经尝试过内容拉伸和项目拉伸。两者都不起作用。

<div class="card-body">

  <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
  <a href="#" class="btn btn-primary">download</a>
</div>
  </div>

</div>

Answer 2

为height:100%; 使用 Bootstrap 4 h-100 类

<div class="card h-100">
  <img src="image1.jpg" class="img-fluid" alt="" />
  <div class="card-body overflow-hidden text-center">
    <h4 class="color-primary">card 1</h4>
    <p></p>
    <a href="" class="btn btn-info"><i class="zmdi zmdi- 
        download"></i>download</a>
  </div>
</div>

通过这样做，即使您的内容长度不同，您的卡片也会匹配您的行高。

Answer 3

如果您希望所有这些包含的高度与您需要在内列上使用 display flex 属性的高度相同

.col-md-3{
  display: flex;
}

-> 同时设置.card的宽度为100%。

.card{
  width: 100%;
}
