W3 schools, Opera Web Standard curriculum, Google Code University, Treehouse

www.w3fools.com   it has created web platform docs as the authoritative resource for documentation. These are community driven efforts maintained by developers who continue to work in the field.

they have at least worked on the primary concern developers had. For many beginners, W3Schools has structured tutorials and playgrounds that offer a decent learning experience. However, it would be a mistake to continue your education without learning from more reputable sources, so when you're ready to level up, move on.

Recently I come across Gymnasium a learning section from Aquent. It has fairly good list of web design and dev courses.

For best online Courses:- UDEMY- Coursera- UDACITYFor best online references:- W3school- TutorialsPoint

I would say that "w3school.com" is the website which offers best and reliable free online web courses for everyone. I myself learn three web courses from that website including HTML5, CSS3 and Javascript.
