WCAG (Web Content Accessibility Guidelines)
01 Definition
WCAG (Web Content Accessibility Guidelines) meaning: A set of published guidelines for making web content usable by people with disabilities.
WCAG is a technical standard from the World Wide Web Consortium (W3C) that lists testable success criteria for accessible web content. It is organized around four principles: perceivable, operable, understandable, and robust. Criteria are graded A, AA, and AAA, with AA the common legal and practical target.
Why it matters
How WCAG (Web Content Accessibility Guidelines) fits the work
Many accessibility laws and procurement rules reference WCAG, so meeting it reduces legal risk and lets more people, including keyboard and screen reader users, complete tasks on your site.
In context
The team audited the checkout flow against WCAG 2.2 AA and fixed low color contrast and missing form labels before launch.
Practical note
Automated checkers catch only a fraction of issues. Manual testing with a keyboard and screen reader is needed to confirm real conformance, and AAA is rarely achievable for a whole site.
