Sometimes it is necessary to refer to a specific section of a page when linking, rather than to the whole page.
You can create a link to any subheading on any page in Wikipedia by including a # character followed by the subheading at the end of a link. For example:
In all section links, be sure to use a piped link for readability, like this:

If a section title changes, rather than go red/inactive, the link will lead to the top of the linked page.
Note that redirects support sections links.
