CSS 100% height with absolute positioning top 0 bottom 0
提问by Brandon Wamboldt
I recently found a site that used a div with position absolute, and the top, left, right and bottom values all set to 0. This created a 100% high, 100% wide div. I am now using this as well, and was wondering if there is any reason not to?
我最近发现一个站点使用了绝对位置的 div，并且顶部、左侧、右侧和底部的值都设置为 0。这创建了一个 100% 高、100% 宽的 div。我现在也在使用这个，想知道是否有任何理由不这样做？
It works really well, it's a simple solution, and the other way I was using had a bug I couldn't fix. The application I'm using this for should only every take up the browser window, and never needs to be bigger.
它工作得非常好，这是一个简单的解决方案，而我使用的另一种方式有一个我无法修复的错误。我使用它的应用程序应该只占用浏览器窗口，永远不需要更大。

This technique works fantastically in modern browsers - there is no reason not to use it.
这种技术在现代浏览器中非常有效——没有理由不使用它。
(unless you care about some really old browsers (IE5/6?), which don't supportsetting topand bottomor leftand righton the same element)
（除非你关心一些非常老的浏览器（IE5/6？），它们不支持在同一个元素上设置top和bottom或left和right）
Here's an answerI wrote earlier today which uses a similar technique.

No, that's fine. Just make sure it doesn't glitch up on different browsers, depending on what you are doing. May I recommend making a jsFiddleand testing it on BrowserLab?
不，没关系。只要确保它不会在不同的浏览器上出现故障，这取决于您在做什么。我可以建议制作一个jsFiddle并在BrowserLab上进行测试吗？
