{{TOC right |limit=2}}

This template is used to present markup or code side by side with the output it renders.

==Usage==
Each cell in the first ("Markup") column uses {{tag|pre|o}} to retain newlines and spaces but styled to allow content to wrap within it. It is usually desirable to escape the content of these cells so that the markup is displayed by wrapping the markup in {{xtag|nowiki}}. It is technically not possible to add this feature to the template.

Each cell in the second ("Renders as") column is usually the unescaped markup copied from the corresponding "Markup" cell before it. There are instances where this may differ:
* If the first line includes wikimarkup that must start on a new line such as #, * or ; then use {{tag|nowiki|s}} before the first line; see examples below.
* Header markup such as {{code|1===}} will show in the page table of contents; use {{tlx|fake heading}}.
* Some templates will place the page in a maintenance category, which is usually undesired:
** Instead of {{tlx|citation needed}}, use {{tlx|fake citation needed}}.
* Some templates may have error checking that places the page in a maintenance category. Suppress the category as possible:
** {{cs1}} templates can suppress the maintenance category by setting {{para|template doc demo|true}}.

The template accepts up to 40 unnamed parameters, resulting in up to 20 rows of examples.

===Limitations===
===={{xtag|nowiki}}====
If you don't wrap the content of the markup cell in {{xtag|nowiki}}, then any template markup will not be escaped, it will be expanded.

This example shows the markup for <nowiki>{{tl|tag}}</nowiki>:
{{Markup
|t1=Renders as |t2=Expected rendering
| {{tl|tag}} | <nowiki>{{tl|tag}}</nowiki>
}}

====HTML entities====
HTML entities are parsed in the markup cell:
{{Markup
|t1=Nowikied markup shows as |t2=Expected markup
| <nowiki> –</nowiki> | &nbsp;&ndash;
}}

To work around this, replace the <code>&</code> with <code>&amp;</code> thus <code>&amp;nbsp;</code> will show as <code>&nbsp;</code>

===Examples===

====Simple====
{{Markup
| <nowiki>'''Bold text'''</nowiki> | '''Bold text'''
| <nowiki>''Italic text''</nowiki> | ''Italic text''
}}
====Short cut====
See [[Template:Mra]].

'''Enter this:'''
<pre>{{subst:mra|'''Bold text'''|''Italic text''}}</pre>
'''To make this:'''
<pre>{{markup|
<nowiki>'''Bold text'''</nowiki>|'''Bold text'''|
<nowiki>''Italic text''</nowiki>|''Italic text''}}</pre>

'''Which renders as:'''
{{markup|
<nowiki>'''Bold text'''</nowiki>|'''Bold text'''|
<nowiki>''Italic text''</nowiki>|''Italic text''}}

====More complex====
Note that {{tl2|Markup}}'s second argument here uses {{tl2|fake heading}} and {{tl2|fake citation needed}}.
{{Markup
| <nowiki>The quick brown fox jumps over the lazy dog.{{#tag:ref|A footnote.<ref>A reference for the footnote.</ref>|group=nb}} The cow jumped over the moon.{{fact}}

== Notes ==
{{reflist|group=nb}}

== References ==
{{reflist}}
</nowiki>
| The quick brown fox jumps over the lazy dog.{{#tag:ref|A footnote.<ref>A reference for the footnote.</ref>|group=nb}} The cow jumped over the moon.{{fake citation needed}}

{{fake heading|sub=2|Notes}}
{{reflist|group=nb}}

{{fake heading|sub=2|References}}
{{reflist|close}}
}}

====Multiple rows====
{{Markup
| The quick brown fox jumps over the lazy dog. | The quick brown fox jumps over the lazy dog.
| The quick brown fox jumps over the lazy dog. | The quick brown fox jumps over the lazy dog.
| The quick brown fox jumps over the lazy dog. | The quick brown fox jumps over the lazy dog.
| The quick brown fox jumps over the lazy dog. | The quick brown fox jumps over the lazy dog.
| The quick brown fox jumps over the lazy dog. | The quick brown fox jumps over the lazy dog.
}}

====With title====
{{Markup |title=Foxes and dogs
| The quick brown fox jumps over the lazy dog. | The quick brown fox jumps over the lazy dog.
}}

====Showing rendered HTML====
When a template is enclosed within {{tl|code}}, it shows the rendered HTML:

{{Markup
| <nowiki>{{cite book |last=White |first=T. H. |title=The Book of Merlyn |year=1977}}</nowiki>
| {{cite book |last=White |first=T. H. |title=The Book of Merlyn |year=1977}}

| <nowiki>{{code|lang=html|{{cite book |last=White |first=T. H. |title=The Book of Merlyn |year=1977}}}}</nowiki>
| {{code|lang=html|{{cite book |last=White |first=T. H. |title=The Book of Merlyn |year=1977}}}}
}}
