The HTML element (or anchor element), with its href attribute, creates a hyperlink to web pages, files, email addresses, locations on the same page, or anything else a URL can address. Content within each should indicate the link's destination.

To jump to a specific section on the same page just add a unique id attribute to the element where you want to jump and put this id prefixed with # as the href attribute of your link.
