Components and patterns that need a guidance change to meet WCAG 2.1

What

We need to change our examples or add improved content to our guidance pages in order to resolve issues from the DAC Audit May 2023.

WCAG criteria

Step-by-step navigation, Step-by-step navigation 'or' headings must be nested under their parent step headings alphagov/govuk-frontend#2794 and usability criteria Step-by-step navigation does not convey all of the information for screen reader users when viewing them as forms alphagov/govuk-design-system#3021
Password (show/hide), Pages with 2+ password fields must use different programmatic labels for 'show' and 'hide' buttons on those password fields alphagov/govuk-frontend#2795
Tabs, Tab components should show visible headings for all sections on mobile screen sizes alphagov/govuk-frontend#2797
Links, Links to Welsh versions of content should be understandable even when out of context alphagov/govuk-frontend-docs#207
Usability criteria
Error message, Error summary, Error messages should use the same label text as the input when referring to an input alphagov/govuk-frontend#2801
Pagination, Pagination for smaller numbers of pages does not show current page number alphagov/govuk-frontend#3682
Character count, Character count is hidden until you approach a character threshold alphagov/govuk-frontend#3689

This work is a continuation from the previous DAC audit cards, alphagov/govuk-frontend#3814, alphagov/govuk-frontend#3592 and alphagov/govuk-frontend#3329.

Why

This work supports our efforts towards the Epic: Update styles, components and patterns to WCAG 2.2 AA alphagov/govuk-frontend#3040.

As we approach the publishing date for WCAG 2.2, we want to ensure our existing govuk-frontend elements are meeting all WCAG 2.1 AA criteria. The only way to pass WCAG 2.2 AA is to also meet all criteria in WCAG 2.1 AA (with one exception, where a criterion is being removed).

We're doing other work to assess where updates are needed to align elements with the 9 new WCAG 2.2 criteria, but we likely don't have capacity to run an internal audit across all of the existing 78 WCAG criteria.
