CrLf (Abbreviation for Carriage return/Line feed)

CrLf (pronounced cur'lif, sometimes crul'lif) is a common combination of ASCII characters used to end one line of text and start a new one: A carriage return (CR) followed by a line feed (LF). More loosely, the term refers to whatever it takes to get from the end of one line of text to the beginning of the next line. In this sense, UNIX uses a bare line feed as its CRLF.

The HTML tag <BR> introduced in HTML 2.0 produces a line break within text flow. Line breaks themselves within HTML documents are not read by browsers.
