Currently 'auto' outline-style (normally for focus ring) and non-auto outline-style behave very differently. The former draws outlines for sub-elements while the latter doesn't. Should we make them the same? Behaviors of other browsers: Outlines: - Firefox (19.0). a single rectangle enclosing the the element and its sub-elements when outline-style!=auto. Doesn't support 'auto'. - IE9: a single rectangle enclosing the element only when outline-style!=auto. Doesn't support 'auto'. IE9 is same as WebKit when outline-style!=auto. Real focus rings (when an element is really focused): - Firefox: position same as outline (enclosing sub-elements), using dotted black-and-white outline style. - IE9: position same as outline (not enclosing sub-elements), using dotted black-and-white outline style. The sub-layer covers part of the focus ring.
