Bootstrap 4 - 将行垂直对齐到容器底部

Question

我无法将一排按钮与容器的底部对齐。

参考下面的截图；一行中有 3 列组成每个部分。该行使用 class 'justify-content-center' 使项目在页面中间居中。

行高取决于内容最多的列。

我的目标是将第二列和第三列的按钮与列的底部对齐，以便与第一列内联。

我已经阅读了 Bootstrap 文档并尝试了许多不同的方法，就像 'align-self-send' 但仍然没有成功。

这是我的标记；

注意：任何自定义 CSS class 都只是样式文本或应用颜色。

您可以使用 flex，将 .d-flex .flex-column 添加到您的 div.package 并将 .flex-grow-1 添加到您想要增长的嵌套元素以填充 space.

在下面的示例中，我只是在 ul 之后添加了一个 div.flex-grow-1，但您可以直接将 class 应用于 ul。

Answer 2

检查下面的代码我在标签后写了描述以供您理解。你必须在你剩下的列中做同样的事情，我猜是包 2 和包 3。

<div class="col-lg-3 col-md-6 m-4 p-2 package package-1 d-flex flex-column"> -- **your col div add d-flex flex-column classes**

... 

    <div class="row mt-auto">  --- **your buttons div add mt-auto class**
          ...
    </div>

</div>
