A hyperlink, commonly referred to as a link, is an element in a digital document or web page that allows users to click and jump to another section within the same document or to a different document or web page. In web pages, hyperlinks are typically created using the HTML tag and can be text-based or associated with images or other elements. Hyperlinks are fundamental to the web, enabling the connection and navigation between different web pages and websites, thus forming the World Wide Web. They are also used in other digital documents like PDFs and ebooks for internal navigation and references.
