Z-index does not work in ie

问题

I have multiple divs in my webpage. there is this javascript slide show and i have put a menu over that slideshow and positioned the div absolute. I have formatted the order with z-indexes. They work perfect in firefox but Internet Explorer does not work on that. what can be the solution.

Thanks in advance.

If you have a full page wrapper div anywhere or can make one or there is an ancestor/parent div you can freely alter,...

Explicitly state position: relative; or position: absolute; and either way also set z-index: 0; or the lowest value you can use.

Also some browsers (especially some IEs) allow a smaller range of z-index.

For sure values between 1 and 100 are safe. Probably more like 1-255 but I vaguely recall some old issue,...
