Reviewing the WCAG
The WCAG is a set of guidelines developed by the World Wide Web Consortium (W3C) to ensure that web content is accessible to people with disabilities. The guidelines are based on four principles:
- Perceivable: Information and user interface components must be presented to users in ways they can perceive
- Operable: User interface components and navigation must be operable
- Understandable: Information and user interface components must be understandable
- Robust: Content must be robust enough to be interpreted by a variety of user agents, including assistive technologies
Further, based on these principles, the guidelines are divided into three levels of conformance:
- Level A: These are the most basic requirements for accessibility
- Level AA: These are more stringent requirements than Level A
- Level AAA: These are the most stringent requirements, more than Levels A and AA
The WCAG is constantly being updated to reflect new technologies...
