Does anyone of you know any useful websites that teach HTML for free? Anything that isn't that complicated, and has spaces for beginners?
The others here have made some good suggestions, but I don't think any of them properly teach HTML, or at least they definitely don't do it quite as well. I extremely super highly recommend this tutorial, and I think this is the only introduction and tutorial for web development anyone ever needs. Just go through their home page, and I guarantee you'll want to give it a shot.
