Worked on the aandrew-me/ytDownloader repository to deliver Gruvbox theme support, enhancing the application's customization and visual accessibility. The project involved implementing a new theme option using CSS variables, updating the HTML structure to accommodate theme selection, and ensuring consistent theming across the user interface. Focused on maintainability, the changes consolidated theme-related formatting and improved CSS value handling. The work leveraged front end development skills, particularly in CSS theming and HTML, to provide users with a more flexible and branded experience. All updates were organized into a single pull request to streamline code review and facilitate a smooth rollout process.
