What WCAG 2.1 Level AA means in plain English
August 20, 2026
WCAG stands for Web Content Accessibility Guidelines. It is published by the W3C and organized into levels: A (minimum), AA (widely expected for public sites), and AAA (stricter, not always practical everywhere).
PlainFix checks against WCAG 2.x A and AA rules that axe-core can detect automatically - things like text alternatives, contrast, form names, and language attributes. Automated checks cannot catch every issue, especially content quality and complex workflows, so treat results as a strong starting point.
When someone asks whether a page meets WCAG AA, they usually mean: does it satisfy those success criteria in a meaningful way for real users? A scan helps you find gaps; applying fixes is what moves you forward.
