Yulia Babkina overhauled the hero section for the olexiy-kireyko/project-DevStudents-JS repository, focusing on improved user experience and accessibility across devices. She revised the HTML markup and applied responsive CSS styling, ensuring the hero area adapts seamlessly to different screen sizes while aligning with design specifications. Her work introduced a secondary hero variant, enabling A/B testing and supporting richer storytelling by toggling between hero-1 and hero-2 sections in code. Throughout the month, Yulia demonstrated proficiency in front end development, HTML, and responsive design, delivering maintainable code that reduced technical debt and enhanced the project’s visual impact without addressing bug fixes.
