The Web Content Accessibility Guidelines (WCAG) are a set of international standards that define how to make web content accessible to people with disabilities, including those who are blind, deaf, or have cognitive disabilities.
WCAG compliance is essential for ensuring that everyone has equal access to information and services on the web. There are three levels of WCAG compliance: A, AA, and AAA.
