;Sections and subsections
Start sections with header lines
Note: Single equal signs give the highest level heading, like the page title; usually projects have the convention not to use them.
<!-- This is the original

== New section ==
=== Subsection ===
==== Sub-subsection ====
-->
<!-- next set
<h1> DO NOT USE THIS </h1>
<h2> New section </h2>
<h3> Subsection </h3>
<h4> Sub-subsection </h4>
-->
<!-- This code prevents confusion in the section editing feature-->
<b><font style="font-size:120%"> New section </font></b>
<b><font style="font-size:110%"> Subsection</font></b>
<b><font style="font-size:100%"> Sub-subsection</font></b>
*Start with a second-level heading (<tt><nowiki>==</nowiki></tt>); don't use first-level headings (=).
*Don't skip levels (for example, second-level followed by fourth-level).
*A [[#Table of contents|table of contents]] will automatically be added to an article that has four or more sections.
*If appropriate, place subsections in an appropriate order. If listing countries, for example, place them in alphabetical order rather than, say, relative to population of [[w:OECD|OECD]] countries, or some random order.
*If you want to keep headings out of the TOC you have to use HTML heading tags and close them without using a slash e.g. <nowiki><h4>heading too low level to be in the toc of large page<h4></nowiki>.

;[[w:newline|Newline]]:
A single
newline
has no
effect on the
layout.
But an empty line
starts a new paragraph,
or ends a list or indented part.
(<nowiki><p></nowiki> disables this paragraphing until <nowiki></p></nowiki> or the end of the section)
(in Cologne Blue two newlines and a div tag give just one newline; in the order newline, div tag, newline, the result is two newlines)
You can make the wikitext more readable by putting in newlines.
You might find this causes future problems — see [[w:Wikipedia:Don't use line breaks]] for details.
* When used in a list, a newline ''does'' affect the layout (See [[Help:List]]).

|-
|You can break lines<br>
without starting a new paragraph.<p>
(The HTML tag <nowiki><br></nowiki> is sufficient. The system produces the XHTML code <nowiki><br /></nowiki>.)</p>
* Please use this sparingly.
* Close markup between lines; do not start a [[Help:Link|link]] or ''italics'' or '''bold''' on one line and close it on the next.

;Sections and subsections
Start sections with header lines
Note: Single equal signs give the highest level heading, like the page title; usually projects have the convention not to use them.
<!-- This is the original
= DO NOT USE THIS =
== New section ==
=== Subsection ===
==== Sub-subsection ====
-->
<!-- next set
<h1> DO NOT USE THIS </h1>
<h2> New section </h2>
<h3> Subsection </h3>
<h4> Sub-subsection </h4>
-->
<!-- This code prevents confusion in the section editing feature-->
<b><font style="font-size:120%"> New section </font></b>
<b><font style="font-size:110%"> Subsection</font></b>
<b><font style="font-size:100%"> Sub-subsection</font></b>
*Start with a second-level heading (<tt><nowiki>==</nowiki></tt>); don't use first-level headings (=).
*Don't skip levels (for example, second-level followed by fourth-level).
*A [[#Table of contents|table of contents]] will automatically be added to an article that has four or more sections.
*If appropriate, place subsections in an appropriate order. If listing countries, for example, place them in alphabetical order rather than, say, relative to population of [[w:OECD|OECD]] countries, or some random order.
*If you want to keep headings out of the TOC you have to use HTML heading tags and close them without using a slash e.g. <nowiki><h4>heading too low level to be in the toc of large page<h4></nowiki>.

;[[w:newline|Newline]]:
A single
newline
has no
effect on the
layout.
But an empty line
starts a new paragraph,
or ends a list or indented part.
(<nowiki><p></nowiki> disables this paragraphing until <nowiki></p></nowiki> or the end of the section)
(in Cologne Blue two newlines and a div tag give just one newline; in the order newline, div tag, newline, the result is two newlines)
You can make the wikitext more readable by putting in newlines.
You might find this causes future problems — see [[w:Wikipedia:Don't use line breaks]] for details.
* When used in a list, a newline ''does'' affect the layout (See [[Help:List]]).

|You can break lines<br>
without starting a new paragraph.<p>
(The HTML tag <nowiki><br></nowiki> is sufficient. The system produces the XHTML code <nowiki><br /></nowiki>.)</p>
* Please use this sparingly.
* Close markup between lines; do not start a [[Help:Link|link]] or ''italics'' or '''bold''' on one line and close it on the next.
