Celia Schmidt-Cisternas contributed to the webkom/lego-webapp project by focusing on UI stability and visual consistency within the application’s front end. She addressed a persistent hover interaction issue in the footer, refining the user experience by restructuring the HTML and CSS to ensure consistent visuals. Additionally, she standardized the warning portal icon and removed unused imports, which reduced styling conflicts and improved code maintainability. Working primarily with React, JavaScript, and CSS, Celia’s efforts resulted in a cleaner, more reliable codebase. Her work demonstrated attention to both user interface detail and long-term maintainability, though the scope was limited to targeted improvements.
