Wikipedia:Tip of the day/May 6
Sometimes it is necessary to refer to a 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 "#" followed by the subheading at the end of a link.
For example: Wikipedia:Community portal#Help out.
In all section links, be sure to use a piped link for readability.
Using a piped link, the previous example looks like this: Help out.
If a section title changes, rather than going red/inactive, the link will lead to the top of the linked page.
