Support for anchor links is available through the "Bookmarks" plugin for Drupal 10. Since the plugin refers to anchor elements as "bookmarks," this documentation will also call them bookmarks.
Contact SCLS to have Bookmarks enabled for your library's website.
An bookmark link, anchor link, or "jump" link points to a specific point on a web page, instead of the default top of page. They are often used in tables of contents and FAQ lists.
