During November 2024, Lena focused on enhancing the Advertisement section in the malme1/project-asdasd11 repository, delivering a feature that improved both styling and responsiveness across mobile, tablet, and desktop devices. She consolidated font usage and image asset handling to minimize layout shifts and optimize load performance, while also refining interactive elements such as Call-to-Action and Contact Us links for consistent behavior at all breakpoints. Lena centralized these updates into a maintainable advertisement.css file, leveraging her skills in CSS, HTML, and responsive design. The work resulted in a more cohesive user experience and streamlined future UI iterations for the product.
