The template {{anchor}} inserts one or more HTML anchors in a page. Those locations can then be linked to using [[#link|...]] syntax.

1. {{anchor|foo}}

could be linked to with [[#foo|...]] from within the same article,
or it could be linked to with [[articlename#foo|...]] from other articles and from redirects.

2. Anchors can be more suitable for inter-article linking than section titles are. For example,

== {{anchor|foo}} Section title ==
Here, links via [[articlename#foo]] would remain valid even if the section were renamed.

3. The template can be used to create up to ten anchors with a single call. For example,

{{anchor|foo|bar|baz}}
will create three anchors that can then be linked to with [[#foo]], [[#bar]] and [[#baz]].
Specifying more than 10 anchors will cause an error message to be displayed.
  • Anchor names that contain # (hash), | (pipe), = (equal) will not work as expected. Most other characters, including white space and punctuation are not a problem.
  • The template can create a maximum of 10 anchors. Specifying more than 10 anchors will result in an error message.
  • Putting each anchor name on separate lines, for example
{{anchor
|humpty
|dumpty}}
will probably not work as expected.
  • Anchor names should be unique on a page, and should not duplicate any heading titles. Duplicate anchors won't work as expected since the #links go to the first anchor with that name. Duplicate anchors also result in invalid HTML, so you can check for duplicate anchors by consulting the W3C Markup Validation Service.
  • If the template is added to a section title then the code will appear in the edit summary when that section is edited, as in "/* {{anchor|Issues}}Limitations */ New issue". This can be fixed by deleting the template code from the edit summary before the changes are saved.
