我有div一些孩子:

<div class="content">
  <h1>heading 1</h1>
  <h2>heading 2</h2>
  <p>Some more or less text</p>
  <a href="/" class="button">Click me</a>
</div>

我想要以下布局:

 -------------------
|heading 1          |
|heading 2          | 
|paragraph text     |
|can have many      |
|rows               |
|                   |
|                   |
|                   | 
|link-button        |
 -------------------

无论有多少文本,p我都希望.button始终保持在底部,而不是将其从流程中取出.我听说这可以通过Flexbox实现,但我无法让它工作.

align-self

在以下代码中,align-self使用flex-wrap: nowrap.

flex-container {
  display: flex;
  flex-wrap: nowrap;
  align-content: flex-start;
  width: 250px;
  height: 250px;
  background-color: silver;
}
flex-item {
  flex: 0 0 50px;
  height: 50px;
  margin: 5px;
  background-color: lightgreen;
}
flex-item:last-child {
  align-self: flex-end;
  background-color: crimson;
}

<flex-container>
  <flex-item></flex-item>
  <flex-item></flex-item>
  <flex-item></flex-item>
  <flex-item></flex-item>
  <flex-item></flex-item>
  <flex-item></flex-item>
</flex-container>

但是当容器切换到时flex-wrap: wrap,align-self属性会失败.

flex-container {
  display: flex;
  flex-wrap: wrap;
  align-content: flex-start;
  width: 250px;
  height: 250px;
  background-color: silver;
}
flex-item {
  flex: 0 0 50px;
  height: 50px;
  margin: …

我正在尝试对齐 Bootstrap 4 卡并与卡本身d-flex一起使用。align-self-stretch这太棒了。

但是，我不知道如何让红色边框的部分浮到底部。仅使用 Bootstrap 4实用程序有什么想法吗？

<div class="col-sm-12 col-md-6 col-lg-4 d-flex align-self-stretch">
    <div class="card shadow-sm mb-4">
        <img src="https://placehold.it/500x300" class="card-img-top" alt="">
        <div class="card-body">
            <h5 class="card-title text-uppercase">Longer title here that wraps two lines</h5>
            <p class="text-muted">Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
            <div class="align-self-end border border-danger">
                <p class="text-uppercase mb-0">Donors: 123</p>
                <p class="text-uppercase">Funded: $1,234</p>
                <a href="#" class="btn btn-info btn-block">View Details</a>
            </div>
        </div>
    </div>
</div>
