Baseado em Locomotive Scroll v5 e Lenis. Ideal para storytelling imersivo e landing pages premium. Locomotive Scroll nasceu no estúdio canadense Locomotive.ca como solução para scroll suave e detecção de viewport. A v5 (2024) é uma reescrita completa baseada em Lenis, com apenas 9.4kB gzipped, dual IntersectionObserver, parallax via data-attributes e progress tracking via CSS variables. Representa a evolução do scroll-hijacking para scroll-enhancement acessível. - Density: 5/10 — Balanced - Variance: 4/10 — Moderate - Motion: 8/10 — Cinematic - **Style:** Smooth Scroll, Parallax, Kinetic, Immersive, Scroll-Driven - **Keywords:** smooth scroll, parallax, infinite scroll, locomotive scroll, lenis, scroll-driven animations, viewport detection, kinetic motion, scroll progress, CSS variables, data attributes, lerp interpolation, scroll speed, scroll hijacking, immersive storytelling - **Era:** 2020s Modern Scroll-Driven - **Light/Dark:** ✓ Full / ✓ Full ## Colors - **Deep Charcoal** (#1A1A2E) — Dark surface, primary background - **Midnight Blue** (#16213E) — Dark surface, primary background - **Pure White** (#FFFFFF) — Light surface, card backgrounds - **Electric Indigo** (#6C63FF) — Accent color, emphasis elements - **Soft Lavender** (#A29BFE) — Extended palette, decorative use - **Warm Coral** (#FF6B6B) — Extended palette, decorative use - **Mint Glow** (#00D2FF) — Extended palette, decorative use - **Pale Smoke** (#F0F0F5) — Extended palette, decorative use ## Typography - **Display / Hero:** Inter — Weight 700, tight tracking, used for headline impact - **Accent:** Space Grotesk — Used for decorative or emphasis text - **Body:** Inter — Weight 400, 16px/1.6 line-height, max 72ch per line - **UI Labels / Captions:** Inter — 0.875rem, weight 500, slight letter-spacing - **Monospace:** JetBrains Mono — Used for code, metadata, and technical values Scale: - Hero: clamp(2.5rem, 5vw, 4rem) - H1: 2.25rem - H2: 1.5rem - Body: 1rem / 1.6 - Small: 0.875rem ## Layout - **Grid:** CSS Grid primary.

Confident, weighted transitions. - **Entry animations:** Fade + translate-Y (16px → 0) over 540ms ease-out. Staggered cascades for lists: 120ms between items. - **Hover states:** Scale(1.03) + shadow lift over 200ms. - **Page transitions:** Fade + slide (300ms). - **Performance:** Only transform and opacity animated. No layout-triggering properties. ## Shapes Base corner radius: 16px. See rounded tokens in front matter for the full scale. ## Components - **Primary Button:** Rounded (16px) shape.
