AspectRatio

Fixed-ratio media and content frame primitive.

Preview

A live, theme-aware example rendered with the published component.

Import

Import from the focused entry point below, or use the same named export from @tavojs/ui. Both are public APIs; measure the built application when comparing their bundle cost.

TSX

tsximport { AspectRatio } from "@tavojs/ui/aspect-ratio";

The component import loads compiled component CSS. Enable tavoUi() for your project theme variables, or import @tavojs/ui/theme.css once for the package default theme. The equivalent CSS-safe component alias is @tavojs/ui/css/aspect-ratio.

When to use

Use it when

Use `AspectRatio` for media, previews, embeds, and thumbnails that need stable dimensions

Choose something else when

Avoid AspectRatio when for interactive form state; combine with form, feedback, or data components instead.

Examples

These examples include imports and local state where interaction requires it. Render the exported component in a page after completing UI installation. Demo state stays in the mounted component; connect file handling, persistence, and data loading to your application as needed.

AspectRatio example

TSXCreate: src/components/examples/AspectRatioExample1.tsx

tsximport { AspectRatio } from "@tavojs/ui/aspect-ratio";

export function AspectRatioExample1() {
  return (
    <>
      <AspectRatio ratio={{ base: "1/1", md: "16/9" }}>
        <img src="/cover.jpg" alt="Product preview" />
      </AspectRatio>
    </>
  );
}

Common props and defaults

A curated starting point. The complete TypeScript API below includes additional props and compound member contracts.

Prop	Type	Default	Description
`className`	`string`	—	Optional class hook applied to the public root element owned by the component.
`ratio`	`ResponsiveValue<number \| "\${number}/\${number}">`	—	Configures ratio for this component.

State ownership and DOM target

Concern	Contract
State	No component state contract is exposed; the application owns the rendered content and surrounding behavior.
DOM target	Public passthrough props target the component root. Treat nested elements and private class names as implementation details.

Anatomy and related components

This component exposes one public component root rather than a compound member API.

Limitations

Avoid AspectRatio when for interactive form state; combine with form, feedback, or data components instead.

Use only the documented props, entry points, and compound members. Internal DOM nesting and CSS class names can change without becoming part of the public component contract.

Accessibility

The wrapper is semantic-neutral; keep accessible labels on the media or content inside.
