FCC-offline: Learn to code without the internet

Someone reached out to me and ask for learning HTML, CSS resources. I pointed him to freeCodeCamp. Though he doesn't always have internet access.

So I created an offline version of freeCodeCamp. With interactive challenges (let him practice, and check his code). It is fully in HTML, CSS, and JavaScript (lightweight, cross-os, zero dependencies).

It is an offline website, generated by markdown files with a small nodejs program. I've managed to create the 10 lessons in the Basic HTML and HTML5: Responsive Web Design series.

Let me know what you think.
