Intermediate and advanced learning references?

Question

Hello to all!

Since Sololearn covers just the basics of the staff, could you give me some links to where I could find some intermediate and advanced readings (ebooks, sites) of HTML, CSS and JS.
Found myself in a pickle a few times in quizzes and got away by using pure logic.
But, I don't like the fact that didn't knew the answer upfront.

P.S. Skip w3schools, already been there.

Thanks!
