+.Sh OUTPUT
+This section documents output details of
+.Nm .
+In general, output conforms to the traditional manual style of a header,
+a body composed of sections and sub-sections, and a footer.
+.Pp
+The text style of output characters (non-macro characters, punctuation,
+and white-space) is dictated by context.
+.Pp
+White-space is generally stripped from input. This can be changed with
+character escapes (specified in
+.Xr mandoc_char 7 )
+or literal modes (specified in
+.Xr mdoc 7
+and
+.Xr man 7 ) .
+.Pp
+If non-macro punctuation is set apart from words, such as in the phrase
+.Dq to be \&, or not to be ,
+it's processed by
+.Nm ,
+regardless of output format, according to the following rules: opening
+punctuation
+.Po
+.Sq \&( ,
+.Sq \&[ ,
+and
+.Sq \&{
+.Pc
+is not followed by a space; closing punctuation
+.Po
+.Sq \&. ,

+.Sq \&: ,
+.Sq \&? ,
+.Sq \&! ,
+.Sq \&) ,
+.Sq \&]
+and
+.Sq \&}
+.Pc
+is not preceded by white-space.
+.
+.Pp
+If the input is
+.Xr mdoc 7 ,
+however, these rules are also applied to macro arguments when appropriate.
+.
+.
+.Ss ASCII Output
+Output produced by
+.Fl T Ns Ar ascii ,
+which is the default, is rendered in standard 7-bit ASCII documented in
+.Xr ascii 7 .
+.Pp
+Font styles are applied by using back-spaced encoding such that an
+underlined character
+.Sq c
+is rendered as
+.Sq _ Ns \e[bs] Ns c ,
+where
+.Sq \e[bs]
+is the back-space character number 8. Emboldened characters are rendered as
+.Sq c Ns \e[bs] Ns c .
+.Pp
+The special characters documented in
+.Xr mandoc_char 7
+are rendered best-effort in an ASCII equivalent.
+.Pp
+Output width is limited to 78 visible columns unless literal input lines
+exceed this limit.
+.
+.
+.Ss HTML Output
+Output produced by
+.Fl T Ns Ar html
+conforms to HTML-4.01 strict.
+.Pp
+Font styles and page structure are applied using CSS2. By default, no
+font style is applied to any text, although CSS2 is hard-coded to format
+the basic structure of output.
+.Pp
+The
+.Pa example.style.css
+file documents the range of styles applied to output and, if used, will
+cause rendered documents to appear as they do in
+.Fl T Ns Ar ascii .
+.Pp
+Special characters are rendered in decimal-encoded UTF-8.
+.
+.
+.Ss XHTML Output
+Output produced by
+.Fl T Ns Ar xhtml
+conforms to XHTML-1.0 strict.
+.Pp
+See
+.Sx HTML Output
+for details; beyond generating XHTML tags instead of HTML tags, these
+output modes are identical.
+.
