Web Content Accessibility Guidelines (WCAG) 2.2
Success Criteria
WCAG
Content is presented in a way that is understandable
- Make text readable and understandable.
- Make content appear and operate in predictable ways.
- Help users avoid and correct mistakes.
When any component receives focus, it does not initiate a change of context
If a Web page contains any of the following help mechanisms, and those mechanisms are repeated on multiple Web pages within a set of Web pages, they occur in the same order relative to other page content, unless a change is initiated by the user:
- Human contact details;
- Human contact mechanism;
- Self-help option;
- A fully automated contact mechanism.
Help mechanisms may be provided directly on the page, or may be provided via a direct link to a different page containing the information.
For this Success Criterion, "the same order relative to other page content" can be thought of as how the content is ordered when the page is serialized. The visual position of a help mechanism is likely to be consistent across pages for the same page variation (e.g., CSS break-point). The user can initiate a change, such as changing the page's zoom or orientation, which may trigger a different page variation. This criterion is concerned with relative order across pages displayed in the same page variation (e.g., same zoom level and orientation).
Reversible: Submissions are reversible.
Checked: Data entered by the user is checked for input errors and the user is provided an opportunity to correct them.
Confirmed: A mechanism is available for reviewing, confirming, and correcting information before finalizing the submission.

Confirmed: A mechanism is available for reviewing, confirming, and correcting information before finalizing the submission.
Information previously entered by or provided to the user that is required to be entered again in the same process is either:
- auto-populated, or
- available for the user to select.
Except when:
- re-entering the information is essential,
- the information is required to ensure the security of the content, or
- previously entered information is no longer valid.
A cognitive function test (such as remembering a password or solving a puzzle) is not required for any step in an authentication process unless that step provides at least one of the following:
- Alternative
- Another authentication method that does not rely on a cognitive function test.
- Mechanism
- A mechanism is available to assist the user in completing the cognitive function test.
- Object Recognition
- The cognitive function test is to recognize objects.
- Personal Content
- The cognitive function test is to identify non-text content the user provided to the Web site.
"Object recognition" and "Personal content" may be represented by images, video, or audio.
- support for password entry by password managers to reduce memory need, and
- copy and paste to reduce the cognitive burden of re-typing.
