移动屏幕上同一行的两张卡[重复]

Question

此代码在桌面视图上运行良好。所有 4 张卡片都显示在同一行。但我想在手机屏幕上的同一行有两张卡，但它会在另一张卡下面 -

<div class="container p-3 my-3">
      <h2 class="text-center">Friendship Quiz</h2>
      <div id="quiz">
        <p class="text-center lead" id="question">What is one thing/activity that makes you relax?</p>
        <div class="row justify-content-center" >

您可以将此引导类添加到每张卡。如col-xs-6表示超小号，适用于手机版。

 <div class="col-sm-2 col-xs-6 mb-3">
         // rest of your code
    </div>
