Designing and developing websites so people with disabilities can perceive, navigate, understand, and interact with the content.
Web accessibility means that people with disabilities can use web content and functionality. It includes perceiving information, navigating, understanding and interacting with a site. The subject is broader than one widget, one automated score or a single group of users.
Barriers can appear in ordinary business tasks. A form may lack understandable labels, a menu may be impossible to operate with a keyboard or important information may exist only in an inaccessible image. Fixing the visible design alone may not resolve the underlying interaction. Test the complete task, including errors and confirmation states.
Accessibility is an ongoing responsibility. New content, third-party tools and template changes can introduce barriers after an earlier review. Automated checks can help identify some issues, but they do not replace appropriate manual evaluation and feedback from people using assistive technologies. A tool’s clean report is not a complete assurance of usability.
Takeaway: Make essential customer journeys usable by people with different access needs. Include accessibility in content, design, development and maintenance rather than treating it as an optional final decoration.
Example
A customer using a keyboard reaches an appointment form but cannot identify the required fields or move out of a custom date picker. The business tests and repairs the actual interaction, not just the colors or text around the form.
What to check
Use relevant standards and a documented evaluation process. Recheck important journeys after changes, and avoid claiming legal compliance or complete accessibility solely because a plugin or automated scan reports success.
