2.4.1 Bypass Blocks

Updated on October 10, 2025

Goal

Provide a way for users — especially keyboard and screen reader users — to bypass repetitive content such as headers, navigation menus, or advertisements, and go directly to the main content of the page.

Key Points

  • Users shouldn’t have to tab through the same navigation links on every page.
  • Common bypass methods:
    • “Skip to main content” link (most common)
    • Landmark roles like main, nav, header, and footer
    • Heading structure for screen reader navigation
  • The bypass mechanism must be keyboard accessible and visible when focused.

Short Summary

Make it easy to jump past repeated blocks of content and reach the main section quickly — essential for efficiency and accessibility.
