I have looked and can't find anything quickly (for 10 points) but I did find this:
http://www.blooberry.com/indexdot/css/properties/position/zindex.htm

And in particular, Browser Peculiarities at the end of this page:

Netscape
4.x:
- Form elements are always rendered on top of absolutely or relatively positioned elements, regardless of where they are located in the document tree or any 'z-index' value specified.
- Negative values are not allowed for the 'z-index' property in these versions - if any z-index values ARE negative, they are placed on the TOP of the z-index stack, in document order.


It should be noted that the value allowed is an integer. Although I can't find anything that specifies it, in usual programming an integer has a limit of 32,767 (positive or negative).

there is no limit.

by: DreamMasterPosted on 2001-05-10 at 16:08:07ID: 6069056

There are not exactly min/max values...(it will accept any values you enter....)

But...(you expected this right?)

Values that are either < -50 or > 50 will not be taken into account anymore....it will show the same as a layer with z-index 50 or -50....

Hope this sheds some light...

Max.

 

by: rhinosaurPosted on 2001-05-10 at 16:36:39ID: 6069122

Where did you get this 50 value from out of interest?

by: DreamMasterPosted on 2001-05-10 at 16:43:51ID: 6069137

found it out one time when I needed more layers....

But the general way for me to use layers and z-index...is not to set any....just place your layers in the order they need to appear on the page...so lowest z-index at the top of your document and highest z-index on the bottom of your document...

Cheers,
Max.

Greetings.
 
This question is still open today, perhaps it was overlooked or just lost in the volumes.  Please return to this question to update it with comments if more information is needed to get your solution.  If you've been helped by the participating expert(s), you may just convert their comment to the accepted answer and then grade and close.  If an answer has ever been proposed you may not have this option to accept the comment as answer, if that is the case, ask the specific expert you wish to award to post an answer.  This benefits others who then search our PAQ for just this solution, and rewards the experts who have provided information.  A win/win scenario.
 
If you wish to award multiple participants, you can do so by creating a zero point question in the Community Support topic area, include this link and tell them which experts you'd like to award what amounts.  If you'd like to delete this question, use the same process as above, but explain why you think it should be deleted.  Here is the Community Support link:   http://www.experts-exchange.com/jsp/qList.jsp?ta=commspt
 
You can always click on your profile to see all your open questions, in the event you also have other open items to be resolved.   If your number of Questions Asked is not equal to the number of Answers Graded, choose to VIEW question history, and you'll quickly be able to navigate to your open items to close them as well.
 
I've had excellent help from experts-exchange through the years and find the real key to getting what I need is to remain active in all my questions, responding with results to suggestions until my solution is found, and recommend that highly.
 
Thank you very much for your responsiveness, it is very much appreciated.

why would anyone ever need more than 100 z-index values anyway?

 

by: dij8Posted on 2001-07-29 at 07:56:32ID: 6331438

8 open questions, 6 B's graded in the last 10, a question only worth 10 points, guess I shouldn't be surprised at this one only getting a B without any comments asking for more detail (http://www.experts-exchange.com/jsp/cmtyQuestAnswer.jsp#3).

Glad to help anyway.

Greetings, rhinosaur.

Thank you for returning and finalizing this question.  However, in all fairness to the experts who spend their time helping, I'd like to point out a few things, and can correct this grade to an A for you.

First, these links about this site, to provide you additional information on the process within Experts-Exchange.  I'd also like to add that "easy" points typically begin at a value of 50 points, you offered 10, and still experts quickly stepped in to help.  Regardless of the grades you choose, the point value remains the same for you, but in terms of awarding experts for their contributions to your questions, the higher the grade, the better the expert point achievement.  When choosing the B grade, you paid 10 points which equals 30 to the expert, an A would have been 40 for the expert, still less than the amount recommended for easy questions.

Apologies, was a bit low on points at the time of asking the question.

Needed to know how many the maximum was as a page is automatically created on the server, so needed to know what to set the maximum value to. To be more specific, we are creating a cascading menu type of afair using divs and z-indexes.

Thanks for your help. Hopefully have now finished my other questions too.

Ben.
