jcorpac Dynamic Interactions
Interactions should provide feedback and delight without being distracting. This skill covers the "Vibe" of the UI.
The Interaction Pipeline
- Trigger: User action (Click, Hover, Scroll).
- Feedback: Intermediate state (Active button, Loading spinner).
- Completion: Final transition (Modal open, Content swap).
CSS vs. JS Animations
- CSS: Best for simple state transitions (
transform,opacity). High performance (handled by the compositor). - Web Animations API (JS): Best for complex, sequenced animations that require logic or randomization.
Best Practices
- Staggering: Animate list items one after another for a more polished feel.
- Easing: Avoid
lineareasing. Useease-outfor items entering andease-infor items exiting. - Respect Preferences: Always wrap animations in
@media (prefers-reduced-motion: no-preference).
