Please suggest some books or some courses I can take online. Given that I know nothing about typography or design.
You can try Lynda.com it is one of the oldest. I found excerpt from this course on youtube https://www.youtube.com/watch?v=UPCIdtrDagc
These days Canva is quite popular. The platform itself is quite user friendly.
Typography is a practice and will improve with your design sense. Try to look out for inspirations.
