Lorem Ipsum is a dummy text commonly used in graphic design, publishing, and web development. It originates from sections 1.10.32 and 1.10.33 of Cicero's "de Finibus Bonorum et Malorum", written in 45 BC, which discusses ethics. The phrase "Lorem ipsum dolor sit amet" is derived from this text and has been used as placeholder text since the Renaissance. It allows designers to focus on layout and visual elements without being distracted by meaningful content.
