A solid, free first step into web development, focused on HTML, CSS, Flexbox and Grid. You build real projects rather than just following along, and you earn a free certificate at the end. The 300-hour estimate is generous — many finish faster.
Good for: Complete beginners who want to build and style web pages from scratch.
Less suitable if: You already know CSS layout, or you want to jump straight into JavaScript or a framework.
Requirements: None — a computer and a browser are enough.
Realistic time: freeCodeCamp lists about 300 hours; many finish sooner. A few weeks to a couple of months part-time.
