Editing Help:Section (section)

== Section ==
=== Subsection ===
==== Sub-subsection ====
</syntaxhighlight>

These are sometimes called "levels" based on the number of equal signs before and after, so that the top "Section" above with two equal signs is a "level two" heading, the subsection is a "level three" heading, and the "sub-subsection" is "level four". The maximum level number is six.

{{anchor|levelone}} Please <em>do not</em> use a "level one" heading (only one equals sign on each side, i.e.: {{!xt|<nowiki>=Heading=</nowiki>}}). This would cause a section heading as large as the page title at the top of the page. 

Heading names of sections (including subsections) should be unique on a page. Using the same heading more than once on a page causes problems:
* An [[Help:Wikilinks|internal link (wikilink)]] to a section, in the form {{xt|<nowiki>[[Article name#Section heading]]</nowiki>}}, will link only to the first section on the page with that name, which may not be the intended target of the link. See [[WP:Linking#Linking to sections of articles|linking to sections of articles]] for further details.
* When a section with a duplicate name is edited, the edit history and summary will be ambiguous as to which section was edited.
* When saving the page after a section edit, the editor's browser may navigate to the wrong section.

=== Numbering ===
Sections are numbered in the table of contents (not applicable in [[Wikipedia:Vector 2022|Vector 2022]]).

=== Sorting order ===
For the ordering of (appendix & footer) sections, see: {{slink|Wikipedia:Manual of Style/Layout|Order of article elements}}.

=== Trailing sections ===
The section and subsection hierarchy in wikitext is mainly determined by the level of the headings, so any text without a new heading is automatically considered part of the preceding section or subsection. This means there is no direct way to indicate that trailing text belongs to the parent section. If making this distinction is important, reordering the text or simply adding another subsection are common approaches.
