html - What does z-index:1001 means in css -

i know z-index defines stack level of box in current context z-index means special(the same 9999)? because used often..

e.g.

.outerbox{ display:block; z-index:1001; }

same purpose z-index: 9999. it's ugly hack moves absolute/relative/fixed elements front.

html css z-index
