在单独的div中对齐元素[重复]

Question

使用 Bootstrap 4，我创建了一个 card-deck 和两个 cards。尽管两个cards 的高度相同，但由于其他元素的文本长度不同，元素不在同一个位置。

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet" />
<div class="card-deck">
  <div class="card" style="margin-top: 0px">
    <div class="card-body">
      <a>
        <img class="card-img" src="{{banner.FeatureImage0.Url}}" alt="Card image cap" style="width:200px; height: 132.531; float: right; margin-left:10px;">
      </a>
      <h5 class="card-title">Get to Know...FirstName LastName</h5>
      <p class="card-text" style="margin-bottom: 20px;">In this interview we feature FirstName LastName, Community Relations and Social Responsibility Officer, Executive Vice President.</p>
      <a class="btn btn-primary" style="color:white !important;">Read More</a>
    </div>
  </div>

  <div class="card" style="margin-top: 0px">
    <div class="card-body">
      <a>
        <img class="card-img" src="{{banner.FeatureImage0.Url}}" alt="Card image cap" style="width:200px; height: 132.531; float: right; margin-left:10px;">
      </a>
      <h5 class="card-title">Questions are more important than answers - August ethics message</h5>
      <p class="card-text" style="margin-bottom: 20px;">The August ethics message comes from FirstName LastName, Wisconsin Region CEO.</p>
      <a class="btn btn-primary" style="color:white !important;">Read More</a>
    </div>
  </div>

</div>

如何确保我的“阅读更多”按钮相互对齐？

Answer 1

您可以使用d-flex flex-column 制作卡片主体的flex-direction 列，然后使用mt-auto (margin-top:auto) 将按钮推到每张卡片的底部...

<div class="container">
    <div class="card-deck">
        <div class="card" style="margin-top: 0px">
            <div class="card-body d-flex flex-column align-items-start">
                <a>
                    <img class="card-img" src="{{banner.FeatureImage0.Url}}" alt="Card image cap" style="width:200px; height: 132.531; float: right; margin-left:10px;">
                </a>
                <h5 class="card-title">Get to Know...FirstName LastName</h5>
                <p class="card-text" style="margin-bottom: 20px;">In this interview we feature FirstName LastName, Community Relations and Social Responsibility Officer, Executive Vice President.</p>
                <a class="btn btn-primary mt-auto" style="color:white !important;">Read More</a>
            </div>
        </div>
        <div class="card" style="margin-top: 0px">
            <div class="card-body d-flex flex-column align-items-start">
                <a>
                    <img class="card-img" src="{{banner.FeatureImage0.Url}}" alt="Card image cap" style="width:200px; height: 132.531; float: right; margin-left:10px;">
                </a>
                <h5 class="card-title">Questions are more important than answers - August ethics message</h5>
                <p class="card-text" style="margin-bottom: 20px;">The August ethics message comes from FirstName LastName, Wisconsin Region CEO.</p>
                <a class="btn btn-primary mt-auto" style="color:white !important;">Read More</a>
            </div>
        </div>
    </div>
</div>

此解决方案不需要更改卡片的结构，因为所有内容都应保留在 card-body 中。

Answer 2

您的卡片内容高度不同。如果您看到，其中一个标题在一个小窗口中占据了 2 行，而另一个则与之相比。有多种方法可以解决这个问题。一种方法是将宽度分配给标题，然后为溢出添加省略号。同样，您可以为身体执行此操作。控制按钮前所有内容的高度后，您的内容将对齐。

省略号：

p {
  width: 200px;
  white-space: nowrap;
  overflow: hidden;
  display: inline-block;
  text-overflow: ellipsis;
  border: 1px solid #ddd;
  margin: 0;
}

Answer 3

卡片已经有一个 flex，所以你可能需要添加一个“文本容器”来填充底部（按钮高度加上一些额外的边距：比如 2.5rem）并使按钮绝对定位到卡片主体底部（相同的距离/size 作为卡体边距：1.5rem)

.card-body {
  position: relative;
}

.card-body .emp-container {
  padding-bottom: 2.5rem;
}

.card-body .btn {
  position: absolute;
  bottom: 1.25rem;
}
