WCAGtekijöihin

WCAGtekijöihin refers to the principles and guidelines established by the Web Content Accessibility Guidelines (WCAG). These guidelines are developed by the World Wide Web Consortium (W3C) to ensure that web content is accessible to people with disabilities. The primary goal is to make the web usable for everyone, regardless of their physical or cognitive abilities.

WCAG is structured around four core principles: perceivability, operability, understandability, and robustness. Perceivability means that users must be able to perceive the information being presented, which includes providing text alternatives for non-text content and making content adaptable. Operability ensures that users can operate the interface, meaning that all functionality must be available through a keyboard and users should have enough time to read and use content. Understandability requires that users can understand the information and the operation of the user interface, which involves making text readable and predictable. Robustness ensures that content can be interpreted reliably by a wide variety of user agents, including assistive technologies.

These principles are further broken down into specific success criteria, which are testable statements that define how to achieve accessibility. WCAG success criteria are categorized into three conformance levels: A (lowest), AA, and AAA (highest). Conformance to WCAG helps organizations meet legal requirements in many countries and demonstrates a commitment to inclusive design. Implementing WCAGtekijöihin benefits not only users with disabilities but also all users by improving the overall quality and usability of web content.
