auto) should create its own zero-based stacking context, and use the integer value specified to decide its place in its parent stacking context. In other words, if the positioned element has a z-index of
auto, its stacking context is inherited from its parent. Internet Explorer, however, creates a new stacking context for elements with any z-index value, including
auto, which wreaks all kinds of havoc and generally causes mayhem in your previously neat and orderly layouts.
