# Button ## Props | Prop | Type | Default | Required | Description | |---|---|---|---|---| | `variant` | `"accent" \| "accent-subtle" \| "neutral" \| "neutral-subtle" \| "ghost" \| "danger" \| "danger-subtle" \| "outline"` | neutral | no | Visual variant. | | `size` | `24 \| 32 \| 40 \| 48` | 32 | no | Height in px (24 \| 32 \| 40 \| 48). | | `href` | `string` | — | no | Render as an anchor with this href (D33). disabled → aria-disabled, no href attribute, pointer-events: none. | | `target` | `string` | — | no | Anchor target; only used with href. | | `rel` | `string` | — | no | Anchor rel; only used with href. | | `ref` | `Ref` | — | no | Forwarded ref to the underlying element. | | `className` | `string` | — | no | Additional CSS class name(s) merged onto the component's root element. | ## Theming Override `--ds-button-*` custom properties at any scope; interactive states derive automatically (L - 0.04 hover, L - 0.08 active). ## Variant guidance - **accent** — Primary action, draws attention. Submit, CTA, main action in a group. - **accent-subtle** — Accent tone, lower visual weight. Selected state, active filter, soft CTA. - **neutral** — Default, structurally present. Secondary actions, toolbar buttons. - **neutral-subtle** — Minimal chrome. Inline actions, table row actions. - **ghost** — No visible container until hover. Icon-only triggers, compact toolbars. - **outline** — Bordered ghost — visible structure, no fill until hover. Marketing CTA, download button; hover fills accent. - **danger** — Destructive action. Delete, remove, disconnect. - **danger-subtle** — Destructive context, low urgency. Warning badges, soft destructive hints. - **success | warning** — Status communication (Tag only). Status badges, labels. ## Rules - One accent per visual group; everything else neutral or ghost. - danger only for actions with real consequences. - Sizes are px numbers (24|32|40|48), never S/M/L. - Typography tokens are --ds-text-{size}-{lineHeight}-{weight}. - Override component tokens (--ds-{component}-*), not semantic tokens, for one-off theming. - --ds-button-font overrides button typography across all sizes (documented D34 override; ember → mono).
