During November 2024, Chesak enhanced the Product Catalog listing in the malme1/project-asdasd11 repository, focusing on responsive front-end development using HTML and CSS. Chesak replaced the previous <picture> image rendering with a div-based approach, enabling greater layout flexibility and improved alignment with branding across devices. The work included updating layout utilities and responsive padding to ensure consistent visuals on both mobile and desktop platforms. Chesak also standardized asset naming conventions, simplifying future maintenance and branding updates. This feature-driven contribution demonstrated depth in responsive design and maintainability, though the scope was limited to a single feature without bug fixes during the period.
