WebDevVikramChoudhary/small_projects_for_beginners_using_Html-Css-Js ? reverse-engineered prompt

Build me a simple beginner friendly website that bundles a handful of small HTML, CSS, and JavaScript demos in one place. I want a clean home page with cards or buttons to open each mini project, like a live clock, a random color generator, a basic calculator, a drum kit you can play with clicks or keyboard keys, a dice game, a CSS grid practice layout, a simple time management or daily planner page, and a section with a full screen video background.

Make each demo feel polished but still easy to understand, with responsive styling, clear labels, and a short note on each page explaining what it does. Keep the interactions smooth and fun, but not overcomplicated. I want this to feel like a collection of small beginner projects someone could learn from and show off.

Please keep it lightweight and easy to run locally in a browser, with sensible file organization and clean code. If anything is unclear, look up current browser friendly patterns online and fill in the gaps in a practical way.
