Often you'll come across some text that you wish to put on a WWW server that is pre-formatted plain text. You could of course go through the text and insert all the necessary HTML formatting commands, but often all you want to do is stop a WWW browser re-formatting it for you. HTML provides the command pair <PRE>...</PRE> to delimit text you don't want re-formatting.
this text will be reformatted by the browser <PRE> and this text will not be reformatted </PRE>would look like:
this text will be reformatted by the browser
and this text
will not be
reformatted
Note that the preformatted text will be displayed in a fixed width
typewriter style font. You should avoid overuse of <PRE>, as it
doesn't allow WWW browsers any leeway in doing anything clever about
line wrapping, and because typewriter style fonts are pretty ugly.
