Focusable Elements - Browser Compatibility Table

The following tables show which elements individual browsers consider focusable or tabbable (keyboard focusable). The tables are based on the focusable test document.

Note that touch devices (without a physical keyboard) only show elements as tabbable (keyboard focusable), that can be navigated to through the on-screen keyboard (or "virtual keyboard").
