Caption

In the context of image accessibility, a caption is text that describes or provides context for an image. Unlike alt text, which is typically hidden and read only by screen readers, captions are often visible to all users and may appear below or alongside an image. Captions can range from brief labels to detailed descriptions depending on the image complexity and context. In HTML, the figcaption element provides a semantic way to associate captions with images within a figure element. The term is distinct from video captions, which provide text alternatives for audio content.
