Contributed front-end enhancements to the NYCU-Service-Learning/nanao-system repository, focusing on usability and layout improvements for accessibility and responsive design. Addressed overflow issues by enabling horizontal scrolling on the Mental Form table and added top padding to its container, improving the user experience on smaller screens. Resolved a layout inconsistency on the Home Page by adjusting the content’s top margin to account for header height, ensuring visual consistency across devices. The work involved applying frontend development skills with React, CSS, and TypeScript, demonstrating attention to cross-device compatibility and accessibility in user interface design within a short project timeframe.
