Animation best practices across easing, timing, properties, transforms, interactions, and accessibility for web interfaces.
Works with
43 rules organized by priority across 7 categories, from critical easing and timing decisions to medium-priority accessibility and polish
Covers easing curves (ease-out default, custom cubic-bezier, spring animations), timing windows (300ms max for UI, 500ms for drawers), and property selection (transform and opacity only)
Includes interaction patterns for gestu

Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionemilkowal-animationsExecute the skills CLI command in your project's root directory to begin installation:
Fetches emilkowal-animations from pproenca/dot-skills and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate emilkowal-animations. Access via /emilkowal-animations in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Comprehensive animation guide for web interfaces based on Emil Kowalski's teachings, open-source libraries (Sonner, Vaul), and his animations.dev course. Contains 43 rules across 7 categories, prioritized by impact.
Reference these guidelines when:
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Easing Selection | CRITICAL | ease- |
| 2 | Timing & Duration | CRITICAL | timing- |
| 3 | Property Selection | HIGH | props- |
| 4 | Transform Techniques | HIGH | transform- |
| 5 | Interaction Patterns | MEDIUM-HIGH | interact- |
| 6 | Strategic Animation | MEDIUM | strategy- |
| 7 | Accessibility & Polish | MEDIUM | polish- |

💡 Pro Tips
✓ Use when
Use when skill capabilities match your task, clear ROI on time saved, and you can validate outputs. Best for repetitive tasks, learning, and quality improvement.
✗ Avoid when
Avoid when task requires deep expertise you can't validate, involves sensitive decisions, or when learning process is more valuable than speed of completion.
