jjacem/ProjetWeb_2A24_2023_2024 — reverse-engineered prompt

Build me a simple but polished website starting from the existing home page. I want it to feel like a real student web project, clean, easy to use, and good on both phone and desktop. Add a proper welcome section, clear navigation, a few useful sections like presentation, projects or services, and a contact area, but keep it lightweight and easy to open in a browser.

Use a nice visual style with good spacing, readable text, and colors that feel modern without being too flashy. If the page is empty or unfinished, fill it with sensible sample content in French so it looks complete and coherent. Make sure buttons and links behave properly, the layout is responsive, and the overall page feels organized and professional.

Please also clean up the code so it is easy to read and maintain, and add a few simple comments where it helps me understand what you changed. If something is unclear, make reasonable choices and keep it simple. You can look up current web design ideas online if needed.
