Fonts can be broadly classified into four main categories: serif, sans serif, script, and decorative. Serif fonts have small strokes or lines at the end of the letters, such as Times New Roman or Georgia. They are often associated with tradition, authority, and formality. Sans serif fonts lack those strokes, such as Arial or Helvetica. They are often seen as modern, clean, and minimalist. Script fonts mimic handwriting or calligraphy, such as Brush Script or Lobster. They can convey elegance, creativity, or casualness. Decorative fonts are designed for special purposes or effects, such as Comic Sans or Impact. They can be fun, quirky, or dramatic, but they should be used sparingly and with caution.
