During February 2025, contributed a comprehensive header revamp and navigation enhancement to the Iryna-Novikova/goit_markup_team_project repository. The work focused on restructuring the header’s HTML to include a logo, a Shop Now call-to-action, and an additional header icon, while implementing responsive CSS to ensure consistent appearance across desktop, tablet, and mobile devices. Expanded navigation options were introduced, including new links and a mobile-friendly burger menu, improving overall usability. Z-index adjustments addressed visual layering issues, ensuring the header maintained proper hierarchy above page content. The project emphasized clean front end development practices using HTML, CSS, and responsive design techniques.
