About Course

Every app you open, every game site you visit, every social feed you scroll started as plain text files written by a human. By the end of this course, you’ll be that human. You’ll go from a blank file to a real, multi-page portfolio website that lives on the internet with its own address you can text to your friends.

This is a hands-on, no-fluff course built for teens who want to actually build things, not just watch. You’ll write genuine HTML for structure, CSS for design, and JavaScript for interactivity, the same three languages that power the entire web. We start with how the web really works, then move through semantic HTML, the CSS box model, Flexbox and Grid layouts, responsive design that looks great on a phone, DOM scripting, and interactive features like a working to-do list.

Every lesson hands you real, correct code you can copy, run, and break. We explain why things work, not just what to type, so you can think like a developer and solve problems on your own. Mistakes are part of the job here; debugging is a skill you’ll practise from day one.

The finale isn’t a toy. You’ll plan, build, and deploy a portfolio site for free using GitHub Pages or Netlify, learn the basics of version control, and even understand how custom domains work. Ready to put something real on the internet? Let’s build.

Interactive JavaScript
Level up your JavaScript with arrays and objects, loops and conditionals, a real interactive to-do list, and your first taste of fetching live data with fetch and JSON.

Build & Launch
Turn skills into a real project: plan a multi-page portfolio, structure files with good practices, learn version control basics, and deploy your site free with GitHub Pages or Netlify.
