During May 2025, Chia-Jung Yu contributed frontend enhancements to the NYCU-Service-Learning/nanao-system repository, focusing on accessibility and responsive design. Using React, TypeScript, and CSS, Chia-Jung enabled horizontal scrolling for the Mental Form table and added top padding to its container, improving usability and reducing overflow on small screens. Additionally, Chia-Jung addressed a layout issue on the Home Page by adjusting the content’s top margin to account for header height, ensuring consistent spacing across devices. The work demonstrated a practical approach to cross-device compatibility and visual consistency, addressing both feature development and bug fixing within a focused project scope.
