Glossary Accessibility

Web accessibility is the practice of designing and developing websites so that they can be used effectively by people with disabilities. This includes ensuring that all users, regardless of their physical or cognitive abilities, can perceive, understand, navigate, and interact with web content. Accessibility is not only about compliance with legal standards but also about enhancing the overall quality of the web experience for everyone.

Core Principles of Web Accessibility (POUR):

  1. Perceivable: Information and user interface components must be presented in ways that users can perceive. This includes providing text alternatives for non-text content and ensuring content is adaptable to different formats.
  2. Operable: Users must be able to navigate and interact with the interface. This involves making all functionality available from a keyboard and providing enough time for users to read and use content.
  3. Understandable: Information must be clear and comprehensible. Consistent navigation patterns and simple language help achieve this goal.
  4. Robust: Content must be robust enough to be interpreted reliably by a wide variety of user agents, including assistive technologies.

Benefits of Accessibility:

  • Inclusivity: Ensures equal access to information and services for people with disabilities, enhancing social equity.
  • Improved Usability: Accessible websites often provide better usability for all users by simplifying navigation and interaction.
  • Legal Compliance: Many regions have laws requiring web accessibility compliance, reducing legal risks for organizations.

Examples:

  • A university website provides transcripts for video lectures to accommodate students who are deaf or hard of hearing.
  • An online retailer implements keyboard navigation features to assist users who cannot use a mouse.

Best Practices:

  • Follow WCAG Guidelines: Adhere to the Web Content Accessibility Guidelines (WCAG) set by the W3C to ensure comprehensive accessibility compliance.
  • Conduct Usability Testing: Involve users with disabilities in testing processes to identify areas for improvement.
  • Use Semantic HTML: Employ semantic HTML elements to convey meaning and structure, aiding assistive technologies in interpreting content correctly.

In conclusion, accessibility is an essential aspect of web design that ensures websites are inclusive and usable by everyone. By following established guidelines and best practices, developers can create digital experiences that accommodate diverse user needs while enhancing overall usability.
