What is <figure> in HTML5

Answer 1

The <figure> tag specifies self-contained content, like illustrations, diagrams, photos, code listings, etc.
While the content of the <figure> element is related to the main flow, its position is independent of the main flow, and if removed it should not affect the flow of the document.
