During a two-month period, Doris contributed frontend improvements to the NYCU-Service-Learning/nanao-system repository, focusing on layout stability and user interface clarity. She addressed UI display issues by dynamically calculating content height with CSS, preventing header overlap and enhancing content visibility. Doris also removed redundant padding on the Stat page to improve layout consistency and resolved homepage whitespace by ensuring the container filled the viewport. Additionally, she refined interactive feedback by updating hover glow effects for body parts, making them clearer and more noticeable. Her work demonstrated attention to maintainable CSS and frontend development practices, resulting in a more reliable user experience.
