Web Design
I strongly recommend checking out the online Responsive Web Design course from FreeCodeCamp and its learner-friendly Community Forum.
Moreover, FreeCodeCamp offers a recognised certification (also for free!) that will look impressive on your CV or Linkedin profile.
You have already covered about 80% of the material in this course, so you should be able to complete it in a few weeks.
Graphic Design
Want to learn about Adobe InDesign, Adobe Illustrator and Adobe Photoshop? Then this is the course and certification for you:

Coursera and Edx
These are two (rival) networks of mostly US universities that offer a wide range of free online courses. However, you need to pay for the certification.
Here are a few examples:
- Programming with JavaScript (Coursera)
- Foundations of Digital Marketing and E-commerce (Coursera)
- CS50's Web Programming with Python and JavaScript (edX)
- Introduction to Web Development with HTML5, CSS3, and JavaScript (edX)
