Gabriella Santos Diniz developed a front-end styling demo for the pablomont/Bolsa-Futuro-Digital-Turma-04-PB repository, focusing on rapid UI prototyping and design discussions. She created a new HTML component, paragraph.html, applying CSS to demonstrate centered text and distinct visual styles for specific classes and IDs. Her work provided a lightweight reference for front-end styling, supporting efficient design reviews and aligning with project guidelines. Using HTML and CSS, Gabriella maintained a clean, single-commit history and adhered to basic version control practices. The scope was limited to one feature, with no bugs addressed, reflecting a focused and foundational engineering contribution.
