During January 2025, Dong worked on the EnCiv/civil-pursuit repository, focusing on enhancing the Tournament component’s user interface. He improved the RoundTracker by adding margin-bottom spacing and migrated fixed pixel margins to rem units, addressing scalability and accessibility across different screen sizes. This approach reduced layout drift and improved readability, aligning the front-end more closely with the project’s design system. Dong utilized JavaScript, CSS, and React to implement these changes, ensuring the UI remained robust and consistent across devices. While no bugs were fixed during this period, his work demonstrated attention to design-system conformance and responsive front-end development practices.
