Applicability

This rule applies to any HTML element that has visible children in the flat tree for which at least one of the following is true:

• It has a horizontal scroll distance greater than the computed left or right padding of the element; or
• It has a vertical scroll distance greater than the computed top or bottom padding of the element

Expectation

Each test target is either included in sequential focus navigation or has a descendant in the flat tree that is included in sequential focus navigation.

Assumptions

This rule assumes that all scrollable elements with visible content need to be keyboard accessible. Scrollable elements that do not need to be keyboard accessible, perhaps because their content is purely decorative, the scroll area is whitespace, or because scroll can be controlled in some other keyboard accessible way such as through a button or custom scrollbar, may fail this rule but still satisfy success criterion 2.1.1 Keyboard.
