That is a paraggraph. A paragraph (from the Ancient Greek παράγραφος, parágraphos, "to write beside") is a self-contained unit of a discourse in writing dealing with a particular point or idea. A paragraph consists of one or more sentences. Though not required by the syntax of any language,paragraphs are usually an expected part of formal writing, used to organize longer prose.
The HTML <p> element represents a paragraph. Paragraphs are usually represented in visual media as blocks of text separated from adjacent blocks by blank lines and/or first-line indentation, but HTML paragraphs can be any structural grouping of related content, such as images or form fields.
Paragraphs are block-level elements, and notably will automatically close if another block-level element is parsed before the closing </p> tag.
