Success Criteria

Refers to WCAG.

Success Criteria are the individual measures of different aspects of web accessibility. The Success Criteria specify the conditions and requirements for content to be considered accessible (or not).

Success Criteria 2.1

Success Criteria 2.1 requires that all functionality be available from a keyboard.

Even if your designing content for a device with no keyboard, you must also include functionality for keyboards.

You should still optimize your content for the other input methods your target device supports, while maintaining the capability for keyboard control.

Requiring keyboard accessibility does not prohibit mouse input nor discourage providing mouse and other input methods in addition to keyboard accessibility.

There are several supporting Success Criteria for 2.1:

2.1.1 Keyboard

                All functionality of the content is available through a keyboard interface without requiring specific timings for individual keystrokes except where the underlying function requires input that depends on the user’s movement and not just the endpoints.

2.1.2 No Keyboard Trap

                If keyboard focus can be moved to a component of the page using a keyboard interface, then focus can be moved away from that component using only a keyboard interface, and, if it requires more than unmodified arrow or tab keys or other standard exit methods, the user is advised of the method for moving focus away.

2.1.3 Keyboard (No Exception)

                All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes.

2.1.4 Character Key Shortcuts

                If a keyboard shortcut is implemented, it must allow for modification, and be active only on focus.

2.4.7 Focus Visible

                Any keyboard operable user interface has a mode of operation where the keyboard focus indicator is visible.
