I bought a course from Colt Steel in 2018 (
https://www.udemy.com/course/the-web-developer-bootcamp/) and was happy with the quality, bought some more courses from him later. He is a good instructor. I have 20+ years experience with programming but learned a lot about the new capabilities of CSS, transformations and new functionality in JavaScript.
You can usually get the courses from Udemy on offers, usually around 15-25$, so register with them or get their app with offers.
