SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Users often can describe what a web animation looks or feels like ("the bouncy thing when a popover opens") but don't know its proper name, making it hard to prompt an AI, brief a designer, or search for implementation guidance. ## Core Features & Use Cases - Reverse glossary lookup: Converts informal, feel-based descriptions of motion effects into exact terms like Pop in, Rubber-banding, Stagger, or Morph. - Disambiguation of close terms: Contrasts easily confused concepts such as Clip-path vs Mask or Shared element transition vs Layout animation so users pick the right word. - Use Case: A product manager writing a spec says "the iOS scroll that resists and snaps back" and receives the term Rubber-banding with a verbatim glossary definition to paste into the ticket. ## Quick Start Ask the assistant what the animation is called when a popover grows out of the button that opened it, and receive the exact term with its definition.

Frequently Asked Questions about animation-vocabulary

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

FAQPage Schema
What is it called when an element bounces into place on a webpage?

That effect is called Pop in, where an element appears with a slight overshoot like it bounces into place. If the motion is physics-driven with overshoot and settling, the related spring term is Bounce.

How do I find the name of an animation effect I can only describe?

Describe what you see or feel, such as springy, slides off, or draws itself in, and the glossary maps that sensation to the exact term. The best match is returned first with one or two close alternates when relevant.

What is the difference between a morph and a crossfade?

A Morph is one shape smoothly turning into another shape, like Dynamic Island. A Crossfade is one element fading out as another fades in at the same spot, with no shape transformation.

What is the iOS scroll effect that snaps back called?

It is called Rubber-banding, the resistance and snap-back felt when dragging past a scroll boundary. It is the signature iOS overscroll behavior.

Does this skill help design or build animations?

No, it only names effects. It is a reverse-lookup glossary for finding the right term to use in prompts, specs, or conversations, not a tool for designing or implementing motion.
