Accessibility overlays and underlying website barriers

Definition

An overlay is a script you add to a site that presents visitors with a toolbar of display preferences, such as larger text or higher contrast, and attempts some automatic repairs to the page. Capabilities and claims vary by product.

When this is relevant

• You are considering one, usually because it is offered as a same-day fix after a demand letter arrives.
• You already have one installed and want to know what it covers.

Why it matters

An overlay's features need to be evaluated alongside the underlying website. Accessibility requires checking whether people can complete tasks with assistive technology, including any effects introduced by the tool.

What to review

• Review the vendor's actual features, test results and public claims.
• Check the site itself, including keyboard use, screen-reader behavior and forms, and record any barriers that need remediation.

Steadwatch's role

• We do not use one, on any site, and would not add one to yours.
• We address accessibility in the site and its components, using automated checks and quarterly manual review. Findings and changes are recorded.

Records you receive

• A monthly test record for each route.
• An accessibility statement describing how the site was tested and reviewed, and what is known to fall short.

Your responsibilities

• Deciding what to do about an overlay you already have, including reviewing any public accessibility or conformance claims it makes for your site. A legal adviser can help with that review.
