Ask HN: What is a good tutorial (like codecademy.com) for learning HTML?

I am trying to find a tutorial for people who haven't a clue what HTML is. I need to be able to give them the site and know that they are learning up to date HTML (unlike if I gave them w3schools) tutorial that would teach them the basics of HTML - basic syntax. These people know absolutely nothing about web development let alone programming. I think Codecademy is top notch for Javascript, but am trying to find a good one for HTML.

Any ideas?
