Guideline 2 (Operable) Flashcards
Success Criterion 2.1.1 Keyboard
Level A
All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes, except where the underlying function requires input that depends on the path of the user’s movement and not just the endpoints.
Success Criterion 2.1.2 No Keyboard Trap
Level A
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.
Success Criterion 2.1.3 Keyboard (No Exception)
Level AAA
All functionality of the content is operable through a keyboard interface without requiring specific timings for individual keystrokes.
Success Criterion 2.1.4 Character Key Shortcuts
Level A
New in 2.1
If a keyboard shortcut is implemented in content using only letter (including upper- and lower-case letters), punctuation, number, or symbol characters, then at least one of the following is true:
Turn off
A mechanism is available to turn the shortcut off;
Remap
A mechanism is available to remap the shortcut to include one or more non-printable keyboard keys (e.g., Ctrl, Alt);
Active only on focus
The keyboard shortcut for a user interface component is only active when that component has focus.
Success Criterion 2.2.1 Timing Adjustable
Level A
For each time limit that is set by the content, at least one of the following is true:
Turn off
The user is allowed to turn off the time limit before encountering it; or
Adjust
The user is allowed to adjust the time limit before encountering it over a wide range that is at least ten times the length of the default setting; or
Extend
The user is warned before time expires and given at least 20 seconds to extend the time limit with a simple action (for example, “press the space bar”), and the user is allowed to extend the time limit at least ten times; or
Real-time Exception
The time limit is a required part of a real-time event (for example, an auction), and no alternative to the time limit is possible; or
Essential Exception
The time limit is essential and extending it would invalidate the activity; or
20 Hour Exception
The time limit is longer than 20 hours.
Success Criterion 2.2.2 Pause, Stop, Hide
Level A
For moving, blinking, scrolling, or auto-updating information, all of the following are true:
Moving, blinking, scrolling
For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential; and
Auto-updating
For any auto-updating information that (1) starts automatically and (2) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it or to control the frequency of the update unless the auto-updating is part of an activity where it is essential.
Success Criterion 2.2.3 No Timing
Level AAA
Timing is not an essential part of the event or activity presented by the content, except for non-interactive synchronized media and real-time events.
Success Criterion 2.2.4 Interruptions
Level AAA
Interruptions can be postponed or suppressed by the user, except interruptions involving an emergency.
Success Criterion 2.2.5 Re-authenticating
Level AAA
When an authenticated session expires, the user can continue the activity without loss of data after re-authenticating.
Success Criterion 2.2.6 Timeouts
Level AAA
New in 2.1
Users are warned of the duration of any user inactivity that could cause data loss, unless the data is preserved for more than 20 hours when the user does not take any actions.
Success Criterion 2.3.1 Three Flashes or Below Threshold
Level A
Web pages do not contain anything that flashes more than three times in any one second period.
Success Criterion 2.3.3 Animation from Interactions
Level AAA
New in 2.1
Motion animation triggered by interaction can be disabled, unless the animation is essential to the functionality or the information being conveyed.
Success Criterion 2.4.1 Bypass Blocks
Level A
A mechanism is available to bypass blocks of content that are repeated on multiple Web pages.
Success Criterion 2.4.2 Page Titled
Level A
Web pages have titles that describe topic or purpose.
Success Criterion 2.4.3 Focus Order
Level A
If a Web page can be navigated sequentially and the navigation sequences affect meaning or operation, focusable components receive focus in an order that preserves meaning and operability.
