During March 2025, Guillaume Baillot developed a multimedia Star Wars Timeline Page for the jabid021/SOPRA-250217-GIT repository, focusing on front-end development using HTML and CSS. The feature presents a chronological timeline of Star Wars movies and series, integrating embedded YouTube trailers and HTML5 audio to create an immersive user experience. Guillaume emphasized clean, accessible styling to ensure readability and ease of navigation, providing a reusable template for future timelines. The work was delivered end-to-end within a single repository, demonstrating proficiency in structuring multimedia content and lightweight UI design, though the scope was limited to one feature without bug fixes during the period.
