提问by Web_Designer
Is there a maximum / minimum possible value for the CSS z-indexproperty?
Do different browsers have different maximum / minimum accepted values?
How will browsers handle a high / low value?
CSSz-index属性是否有最大/最小可能值？
不同的浏览器有不同的最大/最小接受值吗？
浏览器将如何处理高/低值？
I thought I read somewhere once about a max z-indexvalue. Maybe I'm wrong.
Thanks in advance!

Incredibly, this is the chrome's max z-index value.
令人难以置信的是，这是 chrome 的最大 z-index 值。

If you add one more digit it will go to 1e+308
如果您再添加一位数字，它将转到 1e+308

Found some newer information from 2012:
找到了 2012 年的一些新信息：
"Chrome, Opera and IE9 seem to be the only browsers supporting a true infinite value for the z-index, while Firefox is still using 2147483647 and Safari now engages in some strange rounding off behavior after a number exceeds 16 digits in length."
“Chrome、Opera 和 IE9 似乎是唯一支持 z-index 真正无限值的浏览器，而 Firefox 仍在使用 2147483647，而 Safari 现在在数字长度超过 16 位后会进行一些奇怪的四舍五入行为。”
