Developed a responsive chess board rendering and viewer mode UI for the Kaggle/kaggle-environments repository, focusing on enhancing adaptability and user experience across devices. The work involved implementing dynamic sizing of chessboard squares and pieces based on the container’s dimensions, ensuring consistent visual quality regardless of screen size. Leveraging JavaScript for DOM manipulation and CSS styling, the developer introduced conditional rendering of the title and status in viewer mode, improving clarity and usability for users evaluating chess environments. The feature was linked to a specific commit for traceability, reflecting a methodical approach to front end development and maintainable code integration.
