Web motion accessibility, explained.

Practical, tool-independent writing on the animation layer of the web: what breaks, why generated motion breaks it faster, and how to verify it against WCAG — with code that passes. New guides land here.

What is motion slop?

Generated animation that ships broken by default: no reduced-motion guard, infinite attention loops, off-budget effects, hallucinated APIs. Definition, causes, examples, detection, fixes.

How to verify web motion accessibility

A step-by-step process anyone can follow: inventory motion sources, test prefers-reduced-motion for real, check WCAG 2.2.2, 2.3.1 and 2.3.3 with correct levels, and apply code patterns that pass.
