创建响应式物化卡

Question

我们正在使用实体化卡片在我们的网站上显示图像。图片是用户上传的，因此它们有各种不同的尺寸（尽管它们必须大于 250 像素）。

我们能够保持图像的纵横比，这很好，但我们不知道如何做到这一点，同时使每一行的卡片高度相同。这是我们的目标 - 让卡片具有相同的高度（以响应方式），同时保持卡片内图像的纵横比。

我们整天都在搞这个，但没有取得太大进展。任何帮助深表感谢。

使用媒体查询根据屏幕大小设置width/height。 JS 中的示例 Fiddle：https://jsfiddle.net/3yegzwex/

HTML:

<div class="row text-center">
  <div class="col-xs-12 col-md-4 col-sm-12">
    <div class="card" ui-sref='forsaleitem({type:"interior"})'>
      <div class="card-header card-image waves-effect waves-block waves-light">
        <img src="http://images.cdn.stuff.tv/sites/stuff.tv/files/Mercedes-AMG-GT-Interior-illuminated.jpg" class="img-rounded activator resizeimg" alt="Cinque Terre" height="226">
      </div>
      <div class="card-content">
        <h5 class='text-center'>Interior</h5>
      </div>
    </div>
  </div>
  <div class="col-xs-12 col-md-4 col-sm-12">

      </div>
    </div>
  </div>
  <div class="col-xs-12 col-md-4 col-sm-12">
    <div class="card" ui-sref='forsaleitem({type:"performance"})'>
      <div class="card-header card-image waves-effect waves-block waves-light">
        <img src="http://www.autonotas.tv/wp-content/uploads/2015/05/SHW_0323-1024x603.jpg" class="img-rounded activator resizeimg" alt="Cinque Terre" height="226">

      <div class="card-content">
        <h5 class='text-center'>Performance</h5>
      </div>
    </div>
  </div>
</div>

CSS:

.card {
  text-align: center;
}

@media (max-width: 990px) {
  .resizeimg {
    height: auto;
  }
}

@media (min-width: 1000px) {
  .resizeimg {
    width: auto;
    height: 350px;
  }
}

Answer 2

图像真的必须内联吗？还是可以将它们设置为 background-image（因为它们是用户上传的）？如果是这样，您可以将 background-size 属性设置为 cover 来解决问题。也因为 object-fit 是 not widely supported（还）。

cover

A keyword that is the inverse of contain. Scales the image as large as possible and maintains image aspect ratio (image doesn't get squished). The image "covers" the entire width or height of the container. When the image and container have different dimensions, the image is clipped either left/right or top/bottom.

有关演示，请参阅 this updated JSFiddle。 padding-bottom 可以根据您的需要更改为百分比。尝试更改它并查看它的作用。

内联图片

如果图像确实必须内联，您可以应用此解决方案：

.card-image {
  width: 100%;
  padding-bottom: 50%;
  overflow: hidden;
  position: relative;
}

.card-image img {
  width: 100%;
  position: absolute;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
}

图像将被推入 .card-image 并拉伸至所需的宽度。有关演示，请参阅 this JSFiddle。 padding-bottom 可以根据您的需要更改为百分比。
