During May 2025, Youssef Tag Elnasr developed and delivered a dark mode styling feature for the IT-PROJECT repository, focusing on enhancing user experience and accessibility. He implemented a JavaScript-driven toggle that dynamically applies CSS and HTML theming, allowing users to seamlessly switch between light and dark viewing preferences. This approach ensured consistent UI/UX design across all pages and reduced visual fatigue for users. The work demonstrated proficiency in front-end development, particularly in JavaScript, CSS, and UI/UX design. While no bugs were fixed during this period, the feature established a robust foundation for future theming and accessibility improvements.
