A "line break" is a typographical feature that indicates the end of one line of text and the beginning of another. It is commonly used in writing to create a visual separation between thoughts, ideas, or sections. In poetry, line breaks can enhance rhythm and meaning, while in prose, they can improve readability. In digital formats, line breaks are often created by pressing the "Enter" key on a keyboard. In coding, such as in HTML, a line break can be represented by the `<br>` tag. Proper use of line breaks can make text more engaging and easier to follow.
