Paragraphs are the medium-size unit of English text. It is a unit of language larger than a sentence. A new paragraph marks a change of focus, a change of time, a change of place or a change of speaker in a passage of dialogue. A new paragraph begins on a new line, usually indented (set in a little) or with a one-line gap above it. Paragraphing helps readers to follow the story line, argument or dialogue. Use the <p> tag for paragraphs (don't forget the closing </p> tag).
