Custom Elements Skill
This skill provides guidance for defining and using custom HTML elements in this project.
Two Definition Systems
| System | File | Purpose |
|---|---|---|
| HTML Validation | .claude/schemas/elements.json |
Validates custom elements in HTML (html-validate) |
| Custom Elements Manifest | custom-elements.json |
Documents components for IDEs, Storybook, docs |
Both are recommended - elements.json for build-time HTML validation, CEM for runtime tooling.
See MANIFEST.md for Custom Elements Manifest generation.
