and can be operated from the keyboard. Hence if a Web page can be navigated
sequentially and the navigation sequences affect meaning or operation,
focusable components MUST receive focus in an order that preserves meaning
and operability. (Ref. WCAG 2.4.3)

n. For all user interface components, it is a MUST that the name and role
can be programmatically determined; states, properties, and values can be
programmatically set; and notification of changes to these items is available to
assistive technologies. (Ref. WCAG 4.1.2)

o. Any keyboard operable user interface MUST have a mode of operation
where the keyboard focus indicator is visible. This helps the user know which
element among the multiple elements present in the page has focus. For e.g.,
in case of a button a visual change in the button (e.g. color, size) can indicate
that the focus is on the button. (Ref. WCAG 2.4.7)

p. If an input error is automatically detected and suggestions for correction
are known, then the suggestions MUST be provided to the user, unless it
would jeopardize the security or purpose of the content. Input error occurs
if the user omits a certain information that is required by the webpage or the
information provided by the user is not in the correct format or falls outside
the permissible value.This is to ensure that the users receive appropriate
suggestions for correction of input errors if possible. (Ref. WCAG 3.3.3)

q. For Web pages that cause legal commitments or financial transactions for
the user to occur, that modify or delete user-controllable data in data storage
systems, or submit user test responses, at least one of the following MUST be
true: (Ref. WCAG 3.3.4)

• Reversible: Submissions are reversible.

• Checked: Data entered by the user is checked for input errors and the
user is provided with an opportunity to correct them.

• Confirmed: A mechanism is available for reviewing, confirming, and
correcting information before finalizing the submission.

Validation & Testing

Websites should be validated and tested with automatic tools and human review.
Automated methods are generally rapid and convenient but cannot identify all issues.
Human review can help in issues like ensuring clarity of language and ease of navigation.
