cta.js (Call to Animation) is a lightweight 1.2KB JavaScript library that animates any DOM element ('action') onto any other element ('effect') to create smooth action-to-effect transitions. It promotes visual continuity in web apps, inspired by Google Material Design motion principles.

Use cases

• animate a button click onto a modal that opens
• create tile-based app navigation with element transitions
• animate an element into an opening sidebar
• add visual continuity between UI state changes
• guide user attention with choreographed motion between elements
• reverse a previous element-to-element animation

When to choose

• you want a tiny dependency-free animation helper for element-to-element transitions
• you need Material Design-style visual continuity without a full animation framework
• you want graceful fallback in unsupported browsers with no extra code

When to avoid

• you need complex keyframe, timeline, or scroll-based animations
• you already use a full animation library like GSAP or Framer Motion
• you need broad legacy browser support
