css - 如何使这三个图像具有相同的高度和宽度？

Question

我是这里使用 Bootstrap 4 的初学者，我将这些图像放在一张卡片中，我期待让它们具有相同的高度和宽度，但我不确定应该向哪个 div 输入属性让它工作......有人可以帮忙吗？我复制了图片下方的html代码!

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row">
  <div class="col-sm-4 col-md-4 col-lg-4">
    <div class="card">
      <div class="card-body">
        <img class="card-img-top img-responsive" src="https://images.autotrader.com/scaler/620/420/cms/content/articles/oversteer/2017/02-feb/02-24/262253.jpg">
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>
  </div>
  <div class="col-sm-4 col-md-4 col-lg-4">
    <div class="card">
      <div class="card-body">
        <img class="card-img-top img-responsive" src="https://lonestarforklift.com/images/default-source/overview-images/hyundai-80d-9.jpg?sfvrsn=b356117d_0">
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>
  </div>
  <div class="col-sm-4 col-md-4 col-lg-4">
    <div class="card">
      <div class="card-body">
        <img class="card-img-top img-responsive" src="https://www.wagehourinsights.com/wp-content/uploads/sites/697/2014/06/cars-1.jpg">
        <p class="card-text">With supporting text below as a natural lead-in to additional content.</p>
        <a href="#" class="btn btn-primary">Go somewhere</a>
      </div>
    </div>
  </div>
</div>

谢谢大家的关注!

你不能让所有的图像总是具有相同的宽度和高度 但是您可以限制图像尺寸，这样您的 UI 就不会看起来很糟糕

只需添加以下代码即可查看

.card-body .img-responsive{
   max-height: 300px; // you can adjust this height as you want
}

希望对你有帮助
