Does negative z-index have any side effects

Question

I've been searching for a while for an answer to my question:

Does negative z-index have any side effects

And I've already asked before here: Does negative z-index affect performance or compatibility? but it doesn't get enough attention (may be because I mixed things a little bit)

And I wanted to try and asked in a other way.

我正在为跨平台(不同的浏览器,设备)开发一个Web应用程序,有时我需要为z-index属性使用负值,但我担心它是否会对任何/某些产生任何副作用浏览器并打破兼容性.

我希望我明白这个问题:)

Answer 1

在Chrome 1.0,FireFox 3.0,IE 4.0,Opera 4.0,Safari 1.0之后,负值很好.所以基本上如果你不住在2000年你应该没有使用负z指数.MDN似乎没有移动设备的任何数据,但我想,因为大多数移动浏览器也会很好.

根据MDN,浏览器支持负z-index值(CSS 2.1)
