animal-island-ui style

animal-island-ui is a React + TypeScript component library with an original cozy island-style design — 35 components, a single runtime dependency (naive-icons for icons), MIT License.

Pick your scenario first

Both scenarios share the component catalog and the hard rules below.

The style in one paragraph

Warm parchment backgrounds (--animal-bg), earth-brown text (never pure black), mint-teal primary accent, large-radius pill shapes (buttons and inputs are 50px pills; nothing interactive below 12px radius), 3D "game button" stacked shadow on primary buttons only, rounded Nunito + Noto Sans SC typography (body weight 500, headings 600–900), soft cubic-bezier(0.4, 0, 0.2, 1) motion over 0.15–0.35s, and a mix of geometric shapes (swallowtail ribbon Title, digit-tile Countdown) with organic ones (SVG blob-clipped Modal).

Design tokens

The packaged stylesheet declares runtime CSS custom properties on :root — prefix --animal-* — mapped from the library's compile-time tokens. Groups: primary/status colors (with hover/active/bg variants), text colors, backgrounds, borders, radii, spacing, shadows, font family/sizes, motion durations/easing, control heights.

When to use them:

• Styling layout wrappers, custom elements, or app-specific decoration next to library components: use var(--animal-*) instead of raw hex values so custom UI stays on-palette.
• Theming: consumers may override --animal-* variables after importing the library style.
• Re-implementing the style without the library (standalone HTML): a complete :root template with exact values lives in the design system — css-variables.md (raw: https://raw.githubusercontent.com/guokaigdg/animal-island-ui/main/docs/design-system/css-variables.md).

Token values are deliberately not restated here. Exact definitions (every hex/px/ms): design-tokens.md. Pixel-exact per-component CSS (shadows, keyframes, clip-paths): design-system/components/.

Component catalog

Props references are grouped by category under references/components/ (props, legal values, defaults — copied from source):

Hard rules (violations are bugs)

1. Never invent props. Every prop must appear in the component reference (or, in an installed project, in the package's TypeScript declarations — the ground truth).
2. Import the stylesheet exactly once at the app entry: import 'animal-island-ui/style'. Without it components render unstyled.
3. Never use pure black (#000/#111) text or cold gray (#fafafa/#f5f5f5) backgrounds.
4. Never use cold blue focus rings. Focus colors are yellow (#ffcc00 inputs) or the mint primary (buttons).
5. Never give an interactive element corners sharper than 12px radius; buttons and inputs are 50px pills.
6. The 3D pixel-stack shadow belongs to primary / danger-primary buttons only. Cards have no box-shadow. Switch has no outer shadow. Input shadow is opt-in (shadow={true}).
7. Modal keeps its SVG blob clip-path — never a rounded rectangle. Title is a swallowtail ribbon — never a blob, pill, or plain block (Card type="title" no longer exists).
8. Fonts are Nunito + Noto Sans SC; weight never below 400; no monospace for UI text (CodeBlock excepted).
9. Motion uses cubic-bezier(0.4, 0, 0.2, 1) over 0.15–0.35s.
10. Icons come from the external naive-icons package (e.g. import { FlowerIcon } from 'naive-icons') — never emoji, Unicode symbols (✓ ✕ →), hand-rolled SVG, or third-party icon libraries. Prefer naive-icons icon components over emoji everywhere you can.
11. Select is controlled-only (options + value + onChange all required). Controlled Input/Switch/Checkbox/Radio need onChange too.
12. Prefer library components over raw HTML: no visible native <button>, <input>, <select>, checkbox/radio — wrap or use the library equivalents.
13. Import only from the package root and animal-island-ui/style — no deep imports.
14. Style custom elements with var(--animal-*) tokens, not hard-coded colors; never use className/style to override a component's colors, radii, or shadows.
