FreeCodeCamp is a great free resource for learning web development. An article written through their blog Medium talks about the amazing opportunity to learn from some of the best schools, various technical skills. Having taken a number of courses on both edX and Coursera, two popular Massive Open Online Courses (MOOC), I can tell you these are phenomenal resources for learning. If your into something other web development or other technical skills, they also cover other subject, too.
