Horace developed a responsive chart layout for the Statistics page in the NYCU-Service-Learning/nanao-system repository, focusing on frontend development using CSS. He implemented dynamic sizing logic that adjusts the chart container’s height based on the viewport, applying max-height and max-width constraints to maintain a stable layout across devices. This approach reduced vertical overflow and improved readability, directly addressing a user experience risk where the chart ratio calculation could cause excessive page length. Although the work was limited to a single feature over one month, Horace’s solution established a maintainable foundation for future responsive improvements in analytics page design.
