Christopher Perez developed the initial homepage scaffold for the RUMHousing online marketplace, focusing on establishing a reusable HTML structure and integrating external CSS for consistent styling. Working in the uprm-inso4101-2024-2025-s2/semester-project--uprm-online-marketplace repository, he created a main heading, a lodging container, and three sample lodging items, each with descriptive content and a More Info button. He also refreshed the site’s branding by updating references from UPRM Marketplace to RUMHousing in the index.html file. Using front end development skills and HTML, Christopher provided a solid UI foundation, enabling faster future feature iteration and improved branding coherence.
