A friendly, space-efficient rating control that blends a continuous slider with emoji anchors (angry → neutral → happy). The filled track reflects score with a dynamic red→green gradient, while the thumb provides micro-interactions and optional value labels. Designed for quick, low-friction feedback across mobile and web, with full accessibility and analytics hooks.

Functionality

• Continuous or stepped scale (e.g., 0–100, 0–10, or snap to 3/5 anchors).

• Dynamic track color (red→yellow→green) with optional thresholds and tooltips (e.g., “Poor / Okay / Great”).

• Thumb interactions: drag/tap, micro-bounce, haptic tap, hover/focus ring, disabled & read-only states.

• Labels & markers: emoji anchors, tick marks, numeric value or caption above the thumb.

• Accessibility: ARIA slider semantics, Tab/Arrow/Page/Home/End keys, screen-reader announcements, RTL & Reduce Motion.

• Data plumbing: onChange/onChangeEnd, debounce, default value, validation (min/max/required), optimistic update.

• Theming: sizes (S–XL), thumb/track colors, gradient presets, shadows, typography; light/dark ready.

• Analytics & targeting: log view/change/submit, user/session attribution, remote config to control when it appears.

Use cases

• Quick CSAT pulses after tasks (checkout, ticket close, feature use).

• Onboarding friction checks and release feedback.

• Wellness or mood tracking in health/fitness apps.

• Classroom/learning “How confident are you?” moments.

• Kiosk/field data collection where one-handed entry is essential.
