# AspectRatio ## Props | Prop | Type | Default | Required | Description | |---|---|---|---|---| | `ratio` | `number` | — | yes | Width/height ratio, e.g. 16/10 or 4/5. | | `ref` | `Ref` | — | no | Forwarded ref to the frame element. | | `className` | `string` | — | no | Additional CSS class name(s) merged onto the component's root element. | ## Theming Override `--ds-aspect-ratio-*` custom properties at any scope; interactive states derive automatically (L - 0.04 hover, L - 0.08 active). ## 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).
