WCAG

Definition

WCAG, or Web Content Accessibility Guidelines, are a set of international standards designed to ensure that web content is accessible to all users, particularly those with disabilities. These guidelines cover various aspects of web accessibility, including text alternatives for non-text content, adaptable layouts, and navigable interfaces. Adhering to WCAG helps create a more inclusive online environment, aligning with the principles of usability and universal design.
