Developed a new promotional advertisement section for the YurchenkoMaxx/project-7-heaven homepage, focusing on responsive design and maintainable styling. The work involved creating a structured HTML layout and applying CSS to highlight offers, ensuring the section adapted seamlessly across mobile, tablet, and desktop devices. Styling was refactored to improve consistency throughout the project, supporting future scalability and campaign updates. The approach emphasized clean, traceable commits and incremental improvements, with minor bug fixes addressed as part of the development process. This contribution demonstrated proficiency in front end development, particularly in HTML, CSS, and responsive design principles, over a focused one-month period.
