I already have a solid, advanced grasp of web design theory, yet I’m looking to level-up through practice. I want you to build (and guide me through) a hands-on training program centred on HTML/CSS, JavaScript, and fully Responsive Design. The format that drives me best is interactive coding exercises—think live sandboxes, challenge files, and small but meaningful projects that I can iterate on, break, and fix. What I need from you • A structured roadmap that strings concepts together logically, assuming prior knowledge but still covering edge cases and modern best practices. • Purpose-built coding challenges for each topic, complete with starter code, clear success criteria, and concise explanations once a task is solved. • At least one compact capstone project that pulls everything together—ideally a responsive single-page app—from wireframe through deployment. • Real-time or asynchronous feedback on my submitted solutions so I can see exactly where to tighten technique or modernise approach. • All material delivered in files or platforms I can keep using after the engagement (GitHub repo, CodePen templates, or a similar environment are fine). Acceptance criteria • Every exercise must run without extra setup beyond a standard browser and a text editor. • Code samples must follow current HTML5, CSS3, and modern JavaScript (ES6+) conventions. • Final project passes Lighthouse responsive checks and looks clean across at least three breakpoints. If you have an existing library of interactive lessons or can quickly spin one up with tools like CodeSandbox, StackBlitz, or your own custom setup, let me know. I’m ready to start practising right away and will happily hop on a quick call to confirm scope before you draft the first batch of challenges.
