I keep recommending https://developer.mozilla.org/en-US/docs/Web but previously you wrote you learn python. So tutorials for python+web like https://docs.djangoproject.com/ are better. Don't be discouraged by slow learning, you essentially learn 3-5 languages and 100 concepts and every developer started from zero.
