SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill resolves an issue where CSS transitions on elements become "stuck" and fail to animate correctly after navigating between pages in a Single Page Application (SPA).

Core Features & Use Cases

  • SPA Navigation Fix: Ensures CSS transitions (opacity, transform) work reliably after SPA page changes.
  • Reflow Synchronization: Implements a robust method to force browser reflows, synchronizing style updates.
  • Use Case: When elements with fade-in or slide-in animations fail to appear after clicking a navigation link in your React or Vue SPA, this skill will restore their intended animation.

Quick Start

Apply the resetAndInitReveal function to the container element after SPA navigation.

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

FAQPage Schema
Why do CSS transitions get stuck and fail to animate after SPA navigation?▼

CSS transitions get stuck after SPA navigation because style updates batch asynchronously without a reflow. Forcing a synchronous browser reflow before toggling classes ensures the transition animates correctly.

How do I fix opacity or transform transitions that stay in their initial state after a class toggle?▼

Fix stuck opacity or transform transitions by temporarily disabling them, forcing a synchronous reflow to read the element's initial state, then re-enabling transitions to trigger the animation reliably.

Does this CSS transition fix work with React and Vue single page applications?▼

Yes, this CSS transition fix works with React and Vue single page applications. It uses standard JavaScript to manipulate element styles and trigger browser reflows after SPA route changes.

What is the best way to trigger a browser reflow for SPA animation synchronization?▼

The best way to trigger a browser reflow for SPA animation synchronization is reading an element's style property synchronously after updating classes, forcing the browser to recalculate layout before applying transitions.

When should I force a synchronous reflow instead of using CSS animation libraries?▼

Force a synchronous reflow when native CSS transitions fail specifically during SPA page navigation. If standard animations work fine outside of SPA route changes, reflow synchronization directly fixes the batching issue.
