How do I use max-height on <div> element?
提问by Tom
I have a element that is set to contain a table element.
我有一个设置为包含表格元素的元素。
The table element will have anywhere from 0 to upwards of 350 rows.
表格元素将有 0 到 350 行以上的任何位置。
I thought the easiest way to size this DIV element was to apply the max-height property so the DIV element would grow as content was added and add a scroll bar once the content exceeds the max-height property.
我认为调整这个 DIV 元素大小的最简单方法是应用 max-height 属性，这样 DIV 元素就会随着内容的添加而增长，并在内容超过 max-height 属性时添加滚动条。
Code:
代码：
<div style="max-height:209px;overflow:auto;">
<table>
<tr><td>CONTENT</td></tr>
</table>
</div>
What I get instead is that when the content reaches the max-height limit, instead of applying the overflow property, the div element just keeps growing.
我得到的是，当内容达到最大高度限制时，div 元素不会应用溢出属性，而是继续增长。
Of course this is only happening in IE7. Firefox and Safari work as designed.
当然，这只发生在 IE7 中。Firefox 和 Safari 按设计工作。

says that max-height doesn't work with tables. try removing the table that is inside your div.
说 max-height 不适用于表格。尝试删除您的 div 内的表格。
回答by Quentin
IE has supported max-height since IE7 — but only in Standards (AKA Strict) mode.
IE 从 IE7 开始支持 max-height——但仅限于标准 (AKA Strict) 模式。
Make sure you have a Doctype that triggers standards mode as the first thing in your document. (Quirks mode can screw up a lotof things, so never write a document without a Standards mode triggering Doctype unless you have a very very good reason to do so).
确保您有一个 Doctype 触发标准模式作为文档中的第一件事。（怪癖模式可能会搞砸很多事情，所以不要在没有触发 Doctype 的标准模式的情况下编写文档，除非你有很好的理由这样做）。

In addition to max-wdith, you may use the following expression to make sure it is cross browser compatible:
除了 max-wdith 之外，您还可以使用以下表达式来确保它是跨浏览器兼容的：
width: expression(this.width > 400 ? "400px" : true);
height: expression(this.height > 400 ? "400px" : true)

Try setting just the height, and overflow to 'scroll'. Visually, there may not be a difference between the outter-box being full-height, and it notbeing full-height. If that is the case, I would simply refrain from using max-height in place of height.
尝试只设置高度，然后溢出到“滚动”。从视觉上看，外框是全高和不是全高可能没有区别。如果是这种情况，我将避免使用 max-height 代替高度。
Could you show us a bit more of your code, or perhaps an online demonstration? I'd be interested in seeing some of the css, and the doctype.
您能否向我们展示更多您的代码，或者在线演示？我有兴趣查看一些 css 和 doctype。
回答by Emily
What version of IE7 are you using? Max-height support wasn't added until beta 2.
你用的是什么版本的IE7？直到 beta 2 才添加最大高度支持。
The scrollbar shows up in the Compatibility View (the IE7 engine) in IE8.
滚动条显示在 IE8 的兼容性视图（IE7 引擎）中。
Are you sure you aren't using IE6?
你确定你没有使用 IE6 吗？

I just copy and pasted your code, and then dropped in a php loop to create 200 rows or just 2 and it behaves the same in IE 7, Safari, and Firefox.
我只是复制并粘贴您的代码，然后放入 php 循环中以创建 200 行或仅 2 行，它在 IE 7、Safari 和 Firefox 中的行为相同。
You probably aren't declaring a doctype, that creates the problem you're describing in my test.
您可能没有声明文档类型，这会导致您在我的测试中描述的问题。
Or in your realcode you haven't properly defined overflow:auto. Your issue is exactly what would happen if that was the case.
或者在你的真实代码中你没有正确定义溢出：自动。你的问题正是如果是这种情况会发生什么。
It's defined here in the question, but maybe not your code.
它在问题中定义here，但可能不是您的代码。
