Worked on user interface improvements for the TallerDivF repository, focusing on enhancing semantic HTML structure and refining CSS alignment to improve accessibility and content presentation. Applied front-end development skills in HTML and CSS to standardize styling through the use of CSS variables and updated font definitions, ensuring greater visual consistency across the UI. Contributed internal notes and structured comments within the codebase to guide future development and clarify areas needing further refinement. Collaborated through targeted code reviews, emphasizing maintainability and code quality. The work established a solid foundation for ongoing UI enhancements, though no major bugs were reported or fixed during this period.
