Sans-serif is a style of typeface that does not have the small projecting features called "serifs" at the ends of strokes. This gives sans-serif fonts a clean and modern appearance, making them popular for digital displays and signage. Common examples of sans-serif fonts include Arial, Helvetica, and Verdana. These typefaces are often used in web design and user interfaces because they are easy to read on screens. The simplicity of sans-serif fonts can enhance readability, especially at smaller sizes, making them a preferred choice for many designers and typographers.
