            <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>

Answer 2

您可以将列设置为弹性框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 3

您也可以尝试使用绝对CSS功能.bottomposition:absolute;bottom:0;left:0;然后检查位置，改变它以适应你

Answer 4

如果你不想玩css，你可以设置：

class="mb-0"

它会将保证金底部设置为零，并且应该将您的内容降低到它所在的任何单元格的底部。您可以按照类似的方式将其对齐到其他方向：mb，mt，mr，ml
