 | This is a documentation subpage for Template:HTML comment. It contains usage information, categories and other content that is not part of the original page. |
 | This template should always be substituted (i.e., use Template:Tlsp). |
Use this substitution to insert HTML comments (<!-- ... -->) – hidden to readers – into Wikipedia pages.
Usage
{{subst:html comment|Lorem ipsum dolor sit amet}}- ↳
<!-- Lorem ipsum dolor sit amet -->
- ↳
By default a space will be added before and after the given text. Use Template:Tjp to remove it (useful in vertical comments). For example,
{{subst:html comment|collapsed=yes|
Lorem ipsum dolor sit amet
}}
will generate
<!--
Lorem ipsum dolor sit amet
-->
In substitutable templates, use {{{{{|safesubst:}}}HTML comment|...}}.
Notable cases
Using this substitution allows the expansion of MediaWiki commands inside HTML comments, where they would be preserved verbatim otherwise. Compare:
{{subst:html comment|{{subst:FULLPAGENAME}}}}- ↳
<!-- Template:HTML comment -->
- ↳
and:
<!-- {{subst:FULLPAGENAME}} -->- ↳
<!-- {{subst:FULLPAGENAME}} -->
- ↳
