Simple Responsive College Project Website

I’m wrapping up a college assignment and need a small, fully responsive website built from scratch. The site will have three straightforward pages—Home, About, and Contact—styled in a light, clean palette. The Home page should greet visitors with a concise introduction and welcome message; no sliders or heavy animations, just a neat hero section and readable text. The About page can mirror the same visual style while giving me room to drop in a short bio later. On the Contact page I’ll mainly need clear space for my details; if you feel a lightweight form makes more sense, let’s talk, but keep everything minimal. Please write clean, well-commented HTML5, CSS3 (flexbox or grid), and a touch of vanilla JS only where necessary. Make sure it looks polished on mobile, tablet, and desktop breakpoints and hand over all source files in a single folder (or Git repo) so I can submit it easily. No frameworks required; pure code is perfect for this project.
