Answer: Typeface is the overall design and style of a set of letters, numerals, and symbols used in printed or digital media. It includes factors such as the shape of the letters, the spacing between them, and their overall proportions.
Serif font and sans-serif font are two main categories of typefaces. Serif fonts have small decorative lines or flourishes, called serifs, at the ends of their letters. They are generally considered to be more traditional and formal, and are often used in printed materials such as books, newspapers, and magazines.
