| Event name | target | relatedTarget |
|---|---|---|

| Element/focus_event | The EventTarget receiving focus | The EventTarget losing focus (if any) |
| Element/focusin_event | The EventTarget receiving focus | The EventTarget losing focus (if any) |
| Element/focusout_event | The EventTarget losing focus | The EventTarget receiving focus (if any) |
