A caption is a text box that appears below an image or a video. It typically describes the image or explains the purpose of the image. Captions are often used to provide context for the content of the image, or to convey a message that supplements the image. The text usually provides information about the graphic, such as a brief description or the date it was taken. They are often used in photo books, newspapers, and websites.

In some cases, captions may also be used to provide credit to the creator of the image. It can be used to provide information about the people, places, or events depicted in an image or to convey a message or feeling.

Captions are a necessary part of digital storytelling, as they help the reader understand what they are seeing.
