Whitespace character
In computer science, white space is any character or series of characters that represent horizontal or vertical space in typography. When rendered, a whitespace character does not correspond to a visible mark, but typically does occupy an area on a page. For example, the common whitespace symbol , also ASCII 32, represents a blank space punctuation character in text, used as a word divider in Western scripts.
== Overview ==
With many keyboard layouts, a horizontal whitespace character may be entered through the use of a . Horizontal white space may also be entered on many keyboards through the use of the key, although the length of the space may vary. Vertical white space is a bit more varied as to how it is encoded, but the most obvious in typing is the result which creates a 'newline' code sequence in applications programs. Older keyboards might instead say , abbreviating the typewriter keyboard meaning 'Carriage-Return' which generated an electromechanical return to the left stop (CR code in ASCII-hex &0D;) and a line feed or move to the next line (LF code in ASCII-hex &0A;); in some applications these were independently used to draw text cell based displays on monitors or for printing on tractor-guided printers—which might also contain reverse motions/positioning code sequences allowing yesterdays text base fancier displays. Many early computer games used such codes to draw a screen.
The term "white space" is based on the resulting appearance on ordinary paper. However they are coded inside an application, white space can be processed the same as any other character code and programs can do the proper action as defined for the context in which they occur.
