The PRE element tells visual user agents that the enclosed text is "preformatted". When handling preformatted text, visual user agents:
May leave white space intact.
May render text with a fixed-pitch font.
May disable automatic word wrap.
Must not disable bidirectional processing.
Non-visual user agents are not required to respect extra white space in the content of a PRE element.
