Understanding COGA, W3C's cognitive accessibility guidelines
summary
W3C COGA provides concrete patterns: provide alternatives to numbers by pairing temperatures with plain suggestions like “take a jacket” and adding visual scaffolds; date inputs reformat or accept multiple styles; design systems include reader view and selectable fonts for dyslexia; prefer binary options when continua confuse users; document components, measure with usability tests, and test with users with cognitive differences to validate. Prioritize support personalization and instrument outcomes so changes actually improve comprehension.
