Getting started
No. Everything runs in your browser: the editor, the preview, your saved code. If you can open this page, you can start coding.
All 72 lessons and every challenge are free, no credit card required. We may add optional paid extras later, but the core curriculum stays free.
Start with HTML Foundations, lesson one: “Your first webpage.” It takes about eight minutes, and you’ll have written real code by the end of it.
The editor
Yes. The editor autosaves in your browser as you type. Come back tomorrow and your code is right where you left it.
Yes. Hit Share in the playground and you’ll get a link anyone can open to see (and remix) your code.
HTML and CSS update live as you type, but JavaScript re-runs on demand so half-typed code doesn’t error at you. Press Run when you’re ready.
Tutorials & content
HTML Foundations → CSS & Layout → JavaScript Basics. Each track builds on the last, and every lesson tells you exactly what comes next.
Yes. New lessons ship most weeks, and the AI-assisted coding track is being written right now. The newsletter is the easiest way to hear about them.
Reading works great on any device. The editor works on tablets and phones too, though a keyboard makes typing code a lot more pleasant.
Absolutely. Tracks aren’t locked, so jump straight to CSS or JavaScript, and dip back into earlier lessons whenever you hit something unfamiliar.
Account & billing
Not to learn. Lessons and the editor work without one. An account adds progress tracking across devices and is free to create.
