bradtraversy/50projects50days ? reverse-engineered prompt

Build me a simple website that showcases a collection of 50 small front end projects, like a gallery of interactive demos. I want each project to have its own page or section with a clean preview, a title, and a link to open the live demo. Make the main page easy to browse, responsive on mobile, and visually consistent so the projects feel like one polished set even though they each do different things.

The projects should be the usual fun HTML, CSS, and JavaScript exercises, things like expanding cards, progress steps, a search widget, loading animations, sliders, forms, counters, games, and small utility apps. Keep the UI modern but simple, with smooth animations and good spacing. If you need to look up current docs online for anything, go ahead. Focus on making it feel like a complete course style project collection that someone can click through and explore easily.
