# Outline Button

A bordered, transparent-fill medium-emphasis action. Pairs with a SolidButton to establish primary/secondary hierarchy on a surface.

## Installation

This component requires **React** and **Tailwind CSS**. Drop `code.tsx` (or `code.jsx` for JavaScript projects) into your project. Tailwind utility classes are included directly in the component, so no separate CSS file is required.

The component consumes the DevSnips semantic design tokens through Tailwind arbitrary values (for example `bg-[var(--ds-color-primary)]`). Define the `--ds-*` tokens once in your theme — see [React/DESIGN_TOKENS.md](../../../DESIGN_TOKENS.md) for the full token spec.

## Usage

```tsx
<OutlineButton onClick={cancel}>Cancel</OutlineButton>
```

## JavaScript

A `code.jsx` build is provided for projects that ship plain JSX. It exposes the same API and behavior as `code.tsx` — only the TypeScript types are removed.

## Props

| Prop | Type | Default |
|---|---|---|
| `children` | `ReactNode` | — |
| `size` | `ButtonSize` | `md` |
| `block` | `boolean` | `false` |
| `loading` | `boolean` | `false` |
| `disabled` | `boolean` | `false` |
| `iconLeft` / `iconRight` | `ReactNode` | — |

Plus all native `ButtonHTMLAttributes<HTMLButtonElement>`.

## Variants

Single outline variant: transparent fill, `border-strong`, hover lifts to `surface-hover`. See SolidButton/SecondaryButton/GhostButton for the other emphasis levels.

## Sizes

xs (28px) · sm (32px) · **md (36px, default)** · lg (40px) · xl (44px). Horizontal padding scales 8 → 20px; icons scale 14 → 20px.

## States

default · hover · active · focus-visible · loading (spinner + `aria-busy`, layout preserved) · disabled (reduced opacity).

## Accessibility

Renders a native `<button>`. Focus-visible ring uses `color.focus-ring`. Loading sets `aria-busy` and disables to prevent double-submit. Disabled never removes the affordance (reduced opacity, not hidden). Meets the 44px touch target at lg/xl.

## Styling

Tailwind classes are included directly in the component and consume the DevSnips semantic design tokens (`--ds-*`) via arbitrary values. The button themes with the surface automatically in light and dark mode. No component-specific CSS file is needed.

## Design Tokens

See [React/DESIGN_TOKENS.md](../../../DESIGN_TOKENS.md) for the authoritative token specification. This button uses the semantic color, radius, and motion tokens; define them once in your project theme and every button in the family stays in sync.

## Notes

Use as the cancel/secondary action beside a SolidButton. The visible border keeps it a clear affordance without competing with the primary fill.
