During March 2026, this developer refactored the MaxHeightSmoother component in the aymericzip/intlayer repository to use pure CSS height transitions, enabling compatibility with React Server Components and Next.js server-side rendering. By removing all React hooks and the 'use client' directive, the solution reduced client-side JavaScript and improved maintainability. The approach addressed animation dead-time artifacts and enhanced accessibility through proper ARIA attributes, keyboard support, and inert focus management. Utilizing CSS, JavaScript, and TypeScript, the developer implemented a dual-animation strategy and exposed theming variables, while updating Storybook and documentation to reflect the new architecture and improve the developer experience.
