motion_check

Run MotionSpec’s free static motion-accessibility check on a website URL. It scans the site’s linked CSS and style blocks against WCAG 2.2.2 (Pause, Stop, Hide) and WCAG 2.3.3 (reduced motion) and returns a score out of 100 with every candidate and its fix. Static CSS scan only — not a full accessibility audit, not a compliance verdict; nothing submitted is stored.
