Fill-in-the-blank exercises and quick quizzes check your answer the moment you try.
HTML, CSS and JavaScript each add a layer to the same thing. Follow this button from plain HTML to something you can actually click.
The structure of every web page: headings, paragraphs, links and images.
Colors, spacing and layout. Make your HTML look the way you want.
Make pages respond: store values, make decisions, react to clicks.

Lessons you finish are checked off as you go. Your browser remembers them, so you can close the tab and pick up right where you left off.
Every page and every editor works on small screens too.
Typo in “flexbx”? It still finds Flexbox. Press / to search from anywhere.
Exercises tell you right away if you’re right, with a hint if you’re stuck.
Copy a link to any code in the editor and send it to a friend or a mentor.
Start with HTML, style it with CSS, then make it interactive with JavaScript. Each course builds on the last, so you always know what to learn next.
No ads and no tracking cookies. Your code runs in your own browser and is never uploaded.
