Yuya I. enhanced the user interface of the weseek/growi repository by delivering a feature focused on improving the create button’s interaction and visual feedback. Using React, CSS, and TypeScript, Yuya refined the hexagon button’s shape and implemented responsive hover and active states, including a 110% scale effect on hover to align with UI/UX design specifications. The work addressed edge cases in button rendering and ensured cross-browser consistency, resulting in a more intuitive and visually consistent user experience. Through multiple well-documented commits, Yuya improved both the perceived responsiveness of the interface and the maintainability of the codebase.
