html - Img 调整到相同的宽度和高度

Question

是否有任何 img 调整大小以便它们可以具有相同的比例？因为如果它不在相同的图像配给上，就会发生这种情况。我的问题是这一切都变成了这样..

这是我的卡片 html 代码:

 <div class="container">
      <div class="flex-row row">
  <div class="col-xs-6 col-sm-4 col-lg-3">
                    <div class="thumb">
                     <div class="caption card card-default">
                        <div class="card-img">
                          <img src="user_images/<?php echo $row['userPic'] ?>" alt="Card image" class="img-thumbnail" height="100">
                        </div>
                        <!-- Extra div added to enable alignment at bottom -->
                        <div class="excludingImage">
                          <div class="card-body">
                            <p class="card-text" style="color:#00873a"><b><?php echo $cartname ?></b></p>
                            <p class="card-text" style="color:#e81b30"><strike style="color:#aaa">₱<?php echo $orig ?>.00</strike> ₱<?php echo $cartprice ?>.00</p>
                          </div>
                          <div class="card-footer text-center">
                            <a href="shopview.php?prod=<?php echo $cartname ?>"><button type="button" class="btn btn-pink btn-sm"><i class="fa fa-shopping-cart"></i> View Product </button></a></div>
                        </div>
                      </div>
                      <!-- /.caption -->
                    </div>
                    <!-- /.thumbnail -->
                  </div>
               </div></div>

这是我的 CSS:

谢谢!如果我的 img 标签可以调整为相同的宽度和高度，这将对我有很大帮助。所以我的卡片不会像上面那样。

Answer 1

您可以设置一个“框架”来裁剪/隐藏您想要的额外宽度/高度，以便它们都被视为相同的尺寸，您需要将您的 img 包装在 div 并对其应用一些样式。

你可以在这里看到这个概念。我已将图像裁剪到中心，但很容易更改。

HTML

<div class="img-wrap">
  <img src="https://placehold.it/250x200" class="img-wrap__img">
</div>
<div class="img-wrap">
  <img src="https://placehold.it/550x700" class="img-wrap__img">
</div>

CSS

.img-wrap {
  position: relative;
  width: 200px;
  height: 150px;
  overflow: hidden;
}

 .img-wrap__img {
   position: absolute;
   width: 100%;
   top: 50%;
   left: 50%;
   transform: translate(-50%, -50%);
 }
