\@startsection examples ¶Some examples of using \@startsection follow.
This first example puts section titles in large boldface type,
centered. As is typical, it uses \renewcommand because
LaTeX’s standard classes have already defined a \section.
For the same reason it does not define a section counter, or
the commands \thesection and (for the table of contents)
\l@section.
\renewcommand\section{%
\@startsection{section} % name
{1} % level
{0pt} % indent
{-3.5ex plus -1ex minus -.2ex}% beforeskip
{2.3ex plus.2ex} % afterskip
{\centering\normalfont\Large\bfseries}% style
}
This example puts subsection titles in small caps type, inline
with the paragraph, and avoids extra space after punctuation:
\renewcommand\subsection{%
\@startsection{subsection} % name
{2} % level
{0em} % indent
{-1ex plus 0.1ex minus -0.05ex}% beforeskip
{-1em plus 0.2em} % afterskip
{\frenchspacing\scshape} % style
}
The previous examples redefined existing sectioning commands. This
last one defines a new command (\subsubparagraph), illustrating
how to define the needed counter and macros. We use a negative
afterskip to make the heading a run-in.
% show counters even farther down:
\setcounter{secnumdepth}{6}
%
% define the new counter for numbering:
\newcounter{subsubparagraph}[subparagraph]
%
% how to display the number:
\renewcommand{\thesubsubparagraph}
{\thesubparagraph.\@arabic\c@subsubparagraph}
%
% the new command itself, which can just call \@startsection:
\newcommand{\subsubparagraph}{
\@startsection{subsubparagraph}% name
{6} % level
{0em} % indent
{\baselineskip} % beforeskip
{-2em} % afterskip, negative for run-in
{\normalfont\normalsize}% style
}
%
% \l... is how it gets output in the table of contents:
\newcommand*\l@subsubparagraph{\@dottedtocline{6}{10em}{5em}}
%
% \...mark is how it's shown in page headers; in this case, ignored:
\newcommand{\subsubparagraphmark}[1]{}
