html - 如何将div的内容对齐到底部

Question

假设我有以下 CSS 和 HTML 代码:

#header {
  height: 150px;
}

<div id="header">
  <h1>Header title</h1>
  Header content (one or multiple lines)
</div>

标题部分是固定高度，但标题内容可能会改变。

我希望标题的内容与标题部分的底部垂直对齐，因此文本的最后一行“粘”在标题部分的底部。

所以如果只有一行文字，那就是这样的:

-----------------------------
| Header title
|
|
|
| header content (resulting in one line)
-----------------------------

如果有三行:

-----------------------------
| Header title
|
| header content (which is so
| much stuff that it perfectly
| spans over three lines)
-----------------------------

这在 CSS 中如何实现？

Answer 1

相对+绝对定位是最好的选择:

#header {
  position: relative;
  min-height: 150px;
}

#header-content {
  position: absolute;
  bottom: 0;
  left: 0;
}

#header, #header * {
  background: rgba(40, 40, 100, 0.25);
}

<div id="header">
  <h1>Title</h1>
  <div id="header-content">And in the last place, where this might not be the case, they would be of long standing, would have taken deep root, and would not easily be extirpated.

</div>

但是您可能会遇到问题。当我尝试它时，我遇到了下拉菜单出现在内容下方的问题。它只是不漂亮。

老实说，对于垂直居中问题，以及元素的任何垂直对齐问题都不是固定高度，使用表格会更容易。
