What is a Fragment Identifier in a URL? 029

 What is a Fragment Identifier in a URL?

A fragment identifier, also known as an anchor link or hash fragment, is a part of a URL that follows the # symbol and points to a specific section within a web page or document. It doesn't refer to a separate resource but helps navigate within the existing content.

Here's a breakdown of its characteristics and how it works:


  • Follows the # symbol at the end of a URL (e.g.,

  • Can contain letters, numbers, underscores, hyphens, and periods.

  • Needs to correspond to an id attribute value of an element within the HTML document.


  • When a user clicks a link containing a fragment identifier, the browser scrolls the page to bring the targeted element with the matching id attribute into view.

  • Useful for creating internal links within long pages with various sections or creating one-page websites with navigation within the same document.


  • Improves navigation within long pages for better user experience.

  • Allows users to share specific sections of a page easily (e.g., sharing a specific comment in a forum thread).

  • Can aid accessibility by allowing screen readers to jump to specific sections based on id landmarks.

Creating Fragment Links:

  • You can create links with fragment identifiers in HTML using the <a> tag with the href attribute specifying the full URL followed by the # symbol and the target id:


<a href="#section2">Jump to Section 2</a>

  • You can also target elements that don't have a visible representation on the page (e.g., hidden elements or elements used for accessibility purposes).


  • Fragment identifiers don't create separate pages or resources.

  • They solely focus on internal navigation within a single document.

  • Use them effectively to enhance the user experience and accessibility of your web pages.
