如何在引导程序中使卡体在小屏幕中保持水平4

Question

我想如何使用bootstrap 4在小（移动）屏幕上使卡水平。

如下图所示，桌面/大屏幕中的卡垂直和移动/较小屏幕中的卡水平。

 <div class="card-deck py-4">
      <div class="card">
          <img src="../images/providers/tw-s01.svg" style="width:100%" class="card-imm-3"/>
              <div class="card-body">
                  <div class="card-title card-headtext">step 1</div>
                  <div class="card-text cardtext">Register for a free 
                  account</div>
              </div>
            </div>
 </div>

Answer 1

您可以使用像.col-sm这样的引导类（对于小屏幕）.col-lg（对于大型）等结合这些类来调整你的div，为每个设备读取更多信息https://www.w3schools.com/bootstrap/bootstrap_grid_examples.asp

Answer 2

这是你的答案..你必须包括card-group标签才能实现这一点，在使用bootstrap之前4 plz从bootstrap docs和 [nktutorial][2]阅读其文档。

<div class="card-group">
      <div class="card">
        <img class="card-img-top" src=".../100px180/" alt="Card image cap">
        <div class="card-body">
          <h5 class="card-title">Card title</h5>
          <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
          <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
        </div>
      </div>
      <div class="card">
        <img class="card-img-top" src=".../100px180/" alt="Card image cap">
        <div class="card-body">
          <h5 class="card-title">Card title</h5>
          <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
          <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
        </div>
      </div>
      <div class="card">
     <a href="https://nktutorial.com"> <img class="card-img-top" src=".../100px180/" alt="Card image cap"></a>
        <div class="card-body">
          <h5 class="card-title">Card title</h5>
          <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>
          <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
        </div>
      </div>
    </div>
