弹性盒引导图像固定底部

Question

我在图像位置方面遇到了一些问题，我有几列顶部有标题（弹性框），列高度是弹性的，因此它们可以动态调整高度，使它们保持一致。

但是标题下面是图片，我希望图片始终位于底部。

我的代码

您需要通过修改 HTML 或使用 order 属性来重新排序元素。

如果每个card-body 都是一个弹性列，我们可以使用order 属性使图像 div 在每列中显示在最后，然后margin-top:auto 将其推到列的底部。

.card-body {
  flex: 1;
}

.card-body .image {
  order: 2;
  margin-top: auto;
}

基于Paulie_D的answer

您无需额外的 CSS 和一些额外的 CSS 类即可完成此操作： order-1, order-2, order-3 和 mt-auto

<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" />
<div class="container-fluid">
  <div class="row">
    <div class="col-lg-3 col-md-4 col-sm-6 col-xs-12 d-flex flex-column">
      <div class="card-body flex-fill d-flex flex-column">
        <h4 class="order-1 article-preview__headline"><a href="#">title</a></h4>
        <div class="order-3 mt-auto image align-items-end">
          <a href="#"><img class="mt-auto" style="width: 100%; height: auto" src="http://www.fillmurray.com/300/200" alt="Image" /></a>
        </div>
        <a class="order-2 link" href="#">Link goes here</a>
        <hr/>
      </div>
    </div>

    <div class="col-lg-3 col-md-4 col-sm-6 col-xs-12 d-flex flex-column">
      <div class="card-body flex-fill d-flex flex-column">
        <h4 class="order-1 article-preview__headline"><a href="#">title long title long title long title long title long</a></h4>
        <div class="order-3 mt-auto image align-items-end">
          <a href="#"><img class="mt-auto" style="width: 100%; height: auto" src="http://www.fillmurray.com/300/200" alt="Image" /></a>
        </div>
        <a class="order-2 link" href="#">Link goes here</a>
        <hr/>
      </div>
    </div>
