Template:Markup

Template documentation[view] [edit] [history] [purge]

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 <pre> 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 Template:Xtag. 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 <nowiki /> before the first line; see examples below.
• Header markup such as == will show in the page table of contents; use {{fake heading}}.
• Some templates will place the page in a maintenance category, which is usually undesired:
  • Instead of {{citation needed}}, use {{fake citation needed}}.
• Some templates may have error checking that places the page in a maintenance category. Suppress the category as possible:
  • Citation Style 1 templates can suppress the maintenance category by setting |template doc demo=true.

Limitations

Template:Xtag

If you don't wrap the content of the markup cell in Template:Xtag, then any template markup will not be escaped, it will be expanded.

This example shows the markup for {{tl|tag}}:

Renders as	Expected rendering
[markup]	[rendering]

HTML entities

HTML entities are parsed in the markup cell:

Nowikied markup shows as	Expected markup
[markup]	[rendering]

To work around this, replace the & with & thus   will show as  

Examples

Simple

Markup	Renders as
[markup]	[rendering]
[markup]	[rendering]

Short cut

See Template:Mra.

Enter this:

{{subst:mra|'''Bold text'''|''Italic text''}}

To make this:

{{markup|
<nowiki>'''Bold text'''</nowiki>|'''Bold text'''|
<nowiki>''Italic text''</nowiki>|''Italic text''}}

Which renders as:

Markup	Renders as
[markup]	[rendering]
[markup]	[rendering]

More complex

Note that Template:Tl2's second argument here uses Template:Tl2 and Template:Tl2.

Markup	Renders as
[markup]	[rendering]

Multiple rows

Markup	Renders as
[markup]	[rendering]
[markup]	[rendering]
[markup]	[rendering]
[markup]	[rendering]
[markup]	[rendering]

With title

Foxes and dogs

Markup	Renders as
[markup]	[rendering]

Showing rendered HTML

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

Markup	Renders as
[markup]	[rendering]
[markup]	[rendering]

See also

• {{Markup2}} for bulleted and indented markup.
• {{Markupv}} for the vertical presentation (above/below) of markup/code and its output.
• {{Automarkup}} does not require to write the code samples twice.
