During February 2025, the developer contributed to the YurchenkoMaxx/project-7-heaven repository by building a new promotional advertisement section for the homepage. YurchenkoMaxx approached the task by designing a responsive HTML structure and applying CSS styling to highlight offers, ensuring the section adapted seamlessly across mobile, tablet, and desktop devices. The work included refactoring existing styles to improve consistency and maintainability, supporting future marketing campaigns. While no major bugs were addressed, minor fixes were incorporated as part of the development process. The project demonstrated proficiency in front end development, particularly in HTML, CSS, and responsive design principles.
