Ask HN: Good curriculum/guideline to teach your employees how to code?

I am looking for a good curriculum/guideline to follow when teaching the non-technical teams of an organization how to code. It should focus on web technologies, so start with HTML + CSS, then some light JavaScript, then a backend language or (maybe more practical) JS as the backend language as well. Ideally it should have a bigger scope and potentially also include challenges or projects so the class can run over several months and/or employees have some guidance after the class how to keep going.
