SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill prevents entrance and scroll-triggered sections from looking flat or unstructured by providing a consistent animation contract for staggered entry, fire-once reveals, and scroll-driven motion.

Core Features & Use Cases

  • Layered entrance + reveal: Use Layer 2 staggered entry and Layer 3 scroll-triggered reveals with a single attribute contract, including fail-safe behavior when IntersectionObserver is unavailable.
  • Multiple reveal variants: Fade, scale-pop, clip-wipe, and stagger reveal options cover common narrative layouts like cards, dividers, and long-form sections.
  • Scroll UI primitives: Add a scroll progress bar, scroll-snap sections, and a sticky pinned section pattern for guided reading.
  • Decorative scroll motion: Use parallax tiers with a universal document-scroll fallback (and a calm-mode damper) plus native scroll-driven timelines where supported.
  • Expressive SVG motion: Support SVG line draw (and related fills/polygon expansions) for polished diagram and infographic entrances.

Quick Start

Add the foundation contract for motion tokens, then place your staggered list with .va-stagger/.va-stagger-item and mark below-the-fold sections with data-va-reveal="fade", "scale", "clip", or "stagger" to trigger once on scroll.

Frequently Asked Questions about amvcp-anim-entry-scroll

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I implement scroll-reveal animations that trigger only once when a section enters the viewport?▼

Scroll-reveal animations that fire once can be implemented using IntersectionObserver-driven activation with deterministic markup conventions like data-va-reveal attributes, triggering fade, scale, clip, or stagger reveals only when sections cross the viewport threshold.

What is the best way to create staggered entry animations for long-form report pages?▼

Staggered entry animations for long-form pages are created by applying a foundation contract for motion tokens alongside .va-stagger and .va-stagger-item classes, providing layered entrance sequencing with fail-safe behavior when IntersectionObserver is unavailable.

Can I use parallax scroll motion with a fallback when native scroll-driven timelines are not supported?▼

Parallax scroll motion can be implemented with a universal document-scroll fallback and a calm-mode damper, plus native scroll-driven timelines where browser support exists, ensuring decorative scroll motion remains functional across environments.

How do I animate SVG line draw effects for infographic entrances without breaking accessibility?▼

SVG line draw animations for infographic entrances are supported through expressive SVG motion options including related fills and polygon expansions, paired with reduced-motion-safe substitutes to maintain accessibility compliance for users with motion sensitivities.

Does IntersectionObserver-based scroll animation work with reduced motion preferences?▼

IntersectionObserver-based scroll animations must include reduced-motion-safe substitutes, which this approach provides by default, ensuring that staggered entry and scroll-triggered reveals respect user accessibility preferences.

Why do my scroll-triggered animations fail when IntersectionObserver is unavailable in older browsers?▼

Scroll-triggered animations fail without IntersectionObserver due to lacking activation callbacks, but this implementation includes fail-safe behavior that gracefully degrades entrance and reveal animations when the API is unavailable.
