Import

Import the component from its dedicated entry point to keep the dependency and generated bundle explicit.

TSX

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

Normal Tavo.js applications load component styles through the Tavo.js UI plugin. If the application manages component CSS manually, also import @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

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.
