REDUCED MOTION / STATIC RESULT
Reduced motion is enabled. This preview displays the stable result without zoom, displacement or scrambling.
01 / Overview
Fill a progress rail as the preview scrolls. An independent interaction study built for the Resources archive.
02 / How it works
Divide scrollTop by the available scroll distance and use the result as a horizontal scale.
03 / Implementation
Actual React demo source. Import this component with the archive stylesheet and pass variant (readingProgress), values, playing, replay and reduced props. The image demos use /images/resources-bg.png.
