Accessibility widgets: personalization and their limits

An accessibility widget offers extra browser settings, such as font sizes, contrast or a reading mode. You still need to test whether visitors can complete a form or place an order on the actual user journey. Installing a widget does not establish BFSG conformance.

Settings offered by the navable widget

Visitors can adjust their view:

• Change fonts, font sizes and line spacing
• Choose contrasts and colors
• Activate a reading mode
• Highlight links
• Hide distracting images, videos and animations

These settings complement work on your website. Check that text, forms and navigation remain usable with the selected settings.

Runtime adjustments and source code fixes

An embedded widget can change the displayed page during use. These runtime adjustments are not saved as corrections in your templates or components. Re-test their effect after changes to the website.

A missing accessible name, for example, needs a meaningful label. An ARIA attribute alone does not tell you whether the label explains the purpose of the control. The meaning of an image also needs to be assessed in context.

Fix confirmed barriers in your components and content. Record the affected page and state, then repeat the same steps after the fix. This lets you check whether the change resolves the observed problem.

Combining a widget with your testing process

Test important journeys with a keyboard and screen reader, with and without widget settings enabled. Check that controls remain reachable, errors are understandable and dialogs can be operated. Add automated scans alongside these manual checks.

W3C WAI recommends that repairs cover important tasks such as registration and checkout, including every step involved, and that solutions are validated early.

Check affected journeys with the website testing checklist. Audit helps you document technical findings and re-test after code fixes. Find the criteria foundations in the WCAG hub.
