Focus movement relevant
Normative Text
Except for skip links and other elements that are hidden but specifically added to aid keyboard navigation, tabbing does not move the keyboard focus onto content that was not visible before the tab action.
Accordions, dropdown menus, and ARIA tab panels are examples of expandable content. According to this requirement, these would not expand simply because they include an element in the tab-order contained in them. They would either not expand or would not have any tab-order elements in them.
Tests
This section is non-normative.
Procedure
For any interactive element:
- Check that keyboard focus does not disappear into content that is not visible.
- Check that hidden element does not automatically expand (become visible) when the keyboard focus is on it (unless it is a visually hidden element specifically added to aid keyboard navigation) (e.g. skip to main content).
Expected results
- #1 and #2 are true.
