如何将 Bootstrap 列中的元素对齐到底部？

Question

我需要将一个框与 bootstrap 列的 左下角 对齐。谢谢你的帮助。

问题是列没有定义高度。

Answer 1

您可以将列设为 flexbox 并将元素对齐到末尾。

.row {
  background: red;
}

.col-6-md {
  background: lightblue;
  height: 200px;
  display: flex;
}

.bottom {
  background: green;
  align-self: flex-end;
  width: 100px;
  height: 50px;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<div class="row">
  <div class="col-6-md">
    <div class="bottom">Bottom</div>
  </div>
</div>

Answer 2

您也可以尝试使用绝对 CSS 功能

.bottom {
   position: absolute;
   bottom: 0;
   left: 0;
}

然后检查位置，更改它以适合您

    height: 50px;
    width: 50px;

            <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
        </div>
    </div>
</div></div>

Answer 4

如果你不想玩css你可以设置：

class="mb-0"

它会将边距底部设置为零，并且应该将您的内容放到它所在的任何单元格的底部你可以用类似的方式在其他方向对齐它：mb, mt, mr, ml

Answer 5

在 Bootstrap 4 中，您可以在列本身上使用 mt-auto 将项目对齐到底部。它应该已经默认左对齐

Answer 6

在Bootstrap 4

对于整行中的所有列，在行

上使用 align-items-end class

对于单个列，我们在 col

上 align-self-end

Answer 7

所以很酷：

.bottom{
    position:absolute;
    bottom: 0.99rem;
}
