Roman Kokhalepa developed a Homepage Promotional Advertisement Section for the karinahurzan/project-serious-team repository, focusing on responsive layout and accessibility. Using HTML and CSS, Roman implemented a component that displays promotional content consistently across devices, ensuring UI uniformity and improved user exposure to advertisements. The work included accessibility enhancements such as ARIA roles, keyboard navigation, and focus states, addressing usability for all users. Roman iteratively refined the section through multiple commits, resolving alignment and responsiveness issues while applying styling adjustments for various breakpoints and themes. The project demonstrates foundational front end development skills and attention to accessibility in a targeted feature delivery.
