Gabriel Veríssimo delivered a visual refresh for the Index-03 page in the mamazzei-edu/pi-2024-multiplataforma repository, focusing on front-end development and CSS styling. He introduced a dedicated CSS file, styleindex03.css, to centralize and streamline styles, replacing previous inline CSS in index-03.html. His work refined navigation, carousels, cards, and organizer blocks, enhancing visual consistency and maintainability while enabling faster future UI iterations. Gabriel also made minor adjustments to page title capitalization to align with brand guidelines. The project was implemented using HTML and CSS, with the depth of work centered on UI polish and design alignment rather than bug fixes.
