Web accessibility

Understand web accessibility through the steps people take to find information and complete tasks. Learn how WCAG 2.2 is structured and how AI can support evaluation, then define the page, user journey and evidence needed to run your first evaluation prompt.

Check whether functionality can be operated with a keyboard in actual user flows.

Check the paths for moving focus out of widgets and dialogs.

Check options for disabling or remapping single-character shortcuts and restricting when they are active.

Evaluate options for turning off, adjusting, or extending time limits, along with the exceptions.

Check the means of stopping automatic movement and updates.

Allow users to control interruptions except in emergencies.

Preserve data and progress during re-authentication after a session expires.

Inform users how long they can remain inactive before their data may be lost.

Distinguish flash-count evaluation from evaluation against general and red flash thresholds.

Review the AAA requirement for the number of flashes per second.

Check whether motion triggered by interaction can be disabled.

Check the paths for bypassing repeated navigation.

Review whether document titles describe the topic and purpose.

Evaluate whether keyboard navigation order preserves the relationships between information and functionality.

Evaluate link purpose using both the link and its programmatically associated context.

Check for multiple paths to find pages within a site.

Evaluate whether existing headings and labels use meaningful wording.

Check the visual indication of keyboard focus in actual interface states.

Review information that indicates where the current page belongs within the site.

Review the means of identifying a link’s purpose without context.

Explore the AAA criterion for organizing documents with headings by topic.

Evaluate whether fixed elements completely obscure the focused target at AA.

Evaluate even partial obscuring of the focused target at AAA.

Measure the area and contrast between states of AAA focus indicators.

Check for simple-operation alternatives to multipoint and path-based gestures.

Review the timing of press and release events and the means of canceling or undoing actions.

Enable users to find targets by their on-screen labels when using voice control.

Check UI alternatives and disabling options for functionality based on device motion.

Review the enhanced target of 44×44 CSS px and its exceptions.

Check whether using one input method restricts the use of another.

Evaluate single-pointer alternatives to dragging functionality.

Evaluate the 24×24 CSS px requirement and exceptions, including spacing, according to their conditions.
