### 11.2. `\section`

For design considerations of the `\section` command, see Section 3.1, “Sectioning commands”. For the internal command `\@startsection`, see Section 14, “Calling `\@startsection`.

We'll define internal lengths `\pre@sectionskip` and `\post@sectionskip` that are used in both `\section` and `\subsection`.
