Frontend Foundations

A short first step into frontend development. Learn how HTML, CSS, browser JavaScript, responsive layouts, accessibility, and UI state work together before moving into full-stack development. Follow the ideas in small steps: first understand the concept, then practice it in the browser, and finally connect it to a realistic coding problem. Each lesson builds on the previous one so the track becomes a skill you can explain and use, not just a list of terms.
