Sans-serif is a style of typeface that does not have the small projecting features called "serifs" at the ends of strokes. This design gives sans-serif fonts a clean and modern appearance, making them popular for digital screens and signage. Common examples of sans-serif fonts include Arial, Helvetica, and Verdana. These typefaces are often used in various applications, such as websites, advertisements, and user interfaces, due to their readability and simplicity. Sans-serif fonts are particularly effective for conveying information quickly and clearly, making them a preferred choice in contemporary graphic design and typography.
