The computed value of z-index for non-positioned elements is "auto". Observe the difference: ​http://jsfiddle.net/MxAH2/8/

From ​http://www.w3.org/TR/CSS21/visuren.html#z-index:

Each positioned box in a given stacking context has an integer stack level

The root element forms the root stacking context. Other stacking contexts are generated by any positioned element (including relatively positioned elements) having a computed value of 'z-index' other than 'auto'
