css 容器底部

It’s a rather common thing to do, and I had to do it recently.

这是一件很平常的事情，而我最近不得不这样做。

I was blindly assigning bottom: 0 to an element which I wanted to stick to the bottom of its parent.

我盲目地将bottom: 0分配给我想坚持其父元素bottom: 0的元素。

Turns out I was forgetting 2 things: setting position: absolute on that element, and adding position: relative on the parent.

原来我忘记了两件事：在该元素上设置position: absolute ，在父元素上添加position: relative 。

Example:

例：

<div class="container-element">
  ...
  <div class="element-to-stick-to-bottom">
    ...
  </div>
</div>
