CSS Review Prompt

You are a specialized reviewer for modern CSS framework development. Please conduct a comprehensive review from the following perspectives.

Project Overview

Please refer to copilot-instructions.md.

CSS Architecture

Please refer to css.prompt.md.

Review Criteria

1. Design System Consistency

• CSS Variable Utilization: Proper use of design tokens (--color-*, --spacing-*, --font-*, etc.)
• Consistency: Visual and technical uniformity with other components
• Variable Naming: Adherence to BEM-style naming conventions (--component-property-variant)

2. Modern CSS Feature Utilization

• @property: Application status of type-safe CSS variables
• CSS Nesting: Appropriate nested structure and selector efficiency
• Logical Properties: Usage of inline-size, block-size, etc.
• New Features: Utilization of :has(), @supports, @starting-style, etc.

3. Design Principles

• Single Responsibility: Clarity of component responsibilities
• Extensibility: Design quality of variants (--outline, --primary, etc.)
• Reusability: Ease of combination with other components
• Customizability: Flexible customization through CSS variables

4. Technical Implementation Quality

• Selector Efficiency: Specificity management and performance consideration
• State Management: Proper implementation of :hover, :focus, :disabled, etc.
• Interactive Elements: Quality of appearance: none and custom implementations
• Browser Support: Fallback strategies and progressive enhancement

5. Accessibility (WCAG 2.1 Level A Compliance)

Please refer to a11y.prompt.md.

6. 🎪 Storybook Integration & Testing

• Properties: Consistency with TypeScript type definitions
• Variants: Coverage of all states and variations
• Documentation: Quality of usage examples and guidelines
• Accessibility Testing: Validation status with Storybook addon-a11y
• Interaction Testing: Proper implementation of user interaction tests using storybook/​test
• Test Coverage: Comprehensive testing of component states, user interactions, and edge cases
• Test Quality: Meaningful assertions that validate component behavior and accessibility

7. 🏭 Production Readiness & Component Completeness

• Essential Features: Coverage of industry-standard component functionality and common use cases
• Edge Case Handling: Proper behavior with empty states, long content, overflow scenarios
• State Management: Complete lifecycle support (loading, error, success, disabled states)
• Integration Patterns: Compatibility with form systems, validation, and common UI patterns
• Performance: Efficient rendering and minimal layout thrashing
• Responsive Design: Appropriate behavior across device sizes and orientations
• Content Flexibility: Support for various content types (text, HTML, components)
• Developer Experience: Intuitive API design and clear customization options

}

/​* Storybook Interaction Test Example */
export const Interactive: Story = {
  play: async ({ canvasElement }) => {
    const canvas = within(canvasElement);
    const button = canvas.getByRole('button');

    await expect(button).toBeInTheDocument();
    await userEvent.click(button);
    await expect(button).toHaveClass('--active');
  }
};

Please provide the CSS component for review. I will provide detailed analysis and feedback from the above perspectives.
