Aspect Ratio

Use AspectRatio to build consistent, accessible interfaces aligned with the shared design system.

Installation

1. Copy the source code:

• Source in this monorepo: packages/ui/src/components/aspect-ratio.tsx
• Place in your project: components/ui/aspect-ratio.tsx
• Required utility: lib/utils.ts (for cn helper)

2. Update the import paths to match your project structure.

Usage

import { AspectRatio } from "@hoag/ui/components/aspect-ratio";
 
export default function Demo() {
  return (
    <AspectRatio ratio={16 / 9}>
      <div className="flex h-full items-center justify-center rounded-md bg-muted text-sm text-muted-foreground">
        16:9 Preview
      </div>
    </AspectRatio>
  );
}

Import

import { AspectRatio } from "@hoag/ui/components/aspect-ratio";

Basic Example

import { AspectRatio } from "@hoag/ui/components/aspect-ratio";
 
export function AspectRatioBasicExample() {
  return (
    <AspectRatio ratio={16 / 9}>
      <div className="flex h-full items-center justify-center rounded-md bg-muted text-sm text-muted-foreground">
        16:9 Preview
      </div>
    </AspectRatio>
  );
}

Composition Pattern

import { AspectRatio } from "@hoag/ui/components/aspect-ratio";
 
export function AspectRatioSection() {
  return (
    <AspectRatio ratio={1}>
      <div className="flex h-full items-center justify-center rounded-md border bg-background text-sm">
        Square thumbnail
      </div>
    </AspectRatio>
  );
}

Accessibility Checklist

• Verify semantic roles and ARIA attributes for interactive behavior.
• Keep keyboard navigation and focus visibility consistent in all states.
• Ensure color contrast meets accessibility requirements in light and dark themes.
• Provide screen reader context for dynamic state or content changes.

Testing Checklist

• Add render tests for default and key variant states.
• Add interaction tests for callbacks and state transitions.
• Add visual regression checks for responsive and theme variations.
• Cover edge states such as loading, empty, disabled, and error.

Production Tips

• Wrap component logic in feature-level abstractions for domain behavior.
• Keep visual variants centralized to avoid style drift across screens.
• Reuse a single import path strategy for simpler refactors.
• Mirror documented states in Storybook and QA checklists.
