Common questions

Does the ADA apply to my website?

US courts widely treat business websites as places of public accommodation under ADA Title III and apply WCAG 2.1 level AA. If you serve US customers, you're exposed to demand letters.

Do accessibility overlays make me compliant?

No. Overlay/widget tools don't ensure conformance and are themselves frequent lawsuit targets. Fix accessibility in the actual site.

How do I lower my risk?

Meet WCAG 2.1 AA basics (alt text, keyboard, contrast, labeled forms), test with assistive tech, and publish an accessibility statement with a contact to report barriers.
