Skip Links
Skip links are usually hidden navigation links at the top of a page that take keyboard users straight to the main content. Anyone navigating with the Tab key no longer has to work through menu and header first. They count among the recognised techniques for WCAG criterion 2.4.1 (Bypass Blocks).
In practice
A skip link belongs directly after the opening body tag, so it is the first focusable element on the page. It usually stays visually hidden and is revealed on keyboard focus (:focus) – so sighted people navigating by keyboard can see it too. The target is an anchor such as #main on the main content itself. Whether the jump works is checked most reliably with a plain keyboard test using the Tab key. Skip links are not the only route: a clean heading structure or landmark regions also satisfy the Bypass Blocks criterion.
