My very first project on FreeCodeCamp-Tribute Page

This is my very first webpage. By no stretch of the imagination do I consider this to be a final work. I view it as a rough draft. I know it has a great deal of room for improvement. Frankly, right now I feel overwhelmed by the complexity of it. Please feel free to give me any feedback so I can improve upon it. How can I make it more responsive? How can I make the fonts more appealing? How can the layout be improved etc… Any help would be greatly appreciated.
