Basically it means it gets displayed on top of anything with a lower
value of z-index, or auto z-index, that's also below the nearest thing
above it in the document tree that has non-auto z-index.

But often people don't realize that z-index only applies to positioned
elements, so they set it all over the place without it doing anything.

And 999999 is a silly number. Probably 9 would have been fine.
