Help:Sections

Headings break up a page's content into sections, for both visual and organizational benefit to the reader. Section header syntax is used to insert the respective <h1>–<h6> element to the number of equals signs = on each side of the title text. An anchor link is automatically added, along with an "edit" button for logged-in users.

As seen below, the table of contents marks every section:

Styles

	Wikitext Markup	Result	HTML equiv.*	Comments
Heading 1	= Heading 1 =	Heading 1	<h1>Heading 1</h1>	Not recommended for general use. This is the same format as the page title, the weight of which seldom needs to be challenged.
Heading 2	== Heading 2 ==	Heading 2	<h2>Heading 2</h2>	—
Heading 3	=== Heading 3 ===	Heading 3	<h3>Heading 3</h3>
Heading 4	==== Heading 4 ====	Heading 4	<h4>Heading 4</h4>	Potentially skin-dependent, but at least on desktop Vector skin, <h4> through <h6> look the same. Beyond level 4, try to use another way of breaking up the section – options include tables with colspan headers or <thead> text, regular or centered bold text, and so on.
Heading 5	===== Heading 5 =====	Heading 5	<h5>Heading 5</h5>
Heading 6	====== Heading 6 ======	Heading 6	<h6>Heading 6</h6>

* Does not include the class and id attribute values; mw-headline and the section title text, respectively.
