In typography, a bullet or bullet point, •, is a typographical symbol or glyph used to introduce items in a list. The bullet symbol may take any of a variety of shapes, such as circular, square, diamond or arrow. Typical word processor software offers a wide selection of shapes and colors. Lists made with bullets are called bulleted lists. The HTML element name for a bulleted list is "unordered list", because the list items are not arranged in numerical order (as they would be in a numbered list). Usually, bullet points are used to list things.
