What are anchor links in UX design?
Anchor links are hyperlinks that navigate to a specific section within the same page, rather than loading a new page. They work by pointing to the id attribute of a specific HTML element. When activated, the browser scrolls the page to bring that element into view and, in most browsers, updates the URL to include the fragment identifier, allowing the specific section to be linked to directly. Anchor links are used in table of contents navigation for long documents, in FAQ pages where each question links to its answer, and in single-page applications where multiple content sections share a single URL.
When do anchor links improve user experience?
Anchor links improve navigation for long pages where users need to access specific sections without scrolling through the entire content. A table of contents at the top of a long article with anchor links to each section allows users to jump directly to the section they need. This is particularly valuable for reference documentation, legal documents, and comprehensive guides where users rarely read from beginning to end but instead scan and navigate to relevant sections. The URL change that accompanies anchor navigation also means that specific sections can be shared as direct links.
What are the accessibility considerations for anchor links?
Anchor links should move focus to the target element when activated, not just scroll the viewport to it. If focus does not move, keyboard users who activate an anchor link will find their cursor position unchanged and must then navigate forward to reach the linked content. Adding tabindex="-1" to the target element and managing focus programmatically ensures that focus moves correctly. For single-page applications where anchor navigation is managed by JavaScript router libraries, additional work is required to ensure that focus moves appropriately and that screen readers are informed of the navigation through page title updates or other announcements.
