The "line-through" is a typographical feature used to indicate that text has been crossed out or is no longer relevant. It is often represented by a horizontal line drawn through the center of the text. This style is commonly used in documents, online content, and design to show edits, corrections, or items that are no longer applicable. In digital formats, such as word processors or web design, the line-through effect can be applied using specific formatting options or CSS properties. It is particularly useful in lists, such as shopping lists or to-do lists, where completed items can be marked as done by applying the line-through style.
