Rule Description

Each page must have a <main> landmark to provide a mechanism to bypass repeated blocks of content or interface elements (like header and navigation) and quickly arrive at the main content.

The Algorithm, in Simple Terms

Checks for least one of the following features:

  • an internal skip link
  • a heading
  • a landmark region

Why this is Important

Since web sites often display secondary, repeated content on multiple pages (such as navigation links, heading graphics, and advertising frames), keyboard-only users benefit from faster, more direct access to the primary content on a page. This reduces keystrokes and minimizes associated physical pain.

How to Fix the Problem

Ensure each page has a <main> landmark to provide a mechanism to bypass repeated blocks of content or interface elements (like header and navigation) and quickly arrive at the main content.

Ensure each page has a <main> landmark to provide a mechanism to bypass repeated blocks of content or interface elements (like header and navigation) and quickly arrive at the main content.

Landmarks SHOULD be used to designate pre-defined parts of the layout such as the main content section.

A page SHOULD NOT contain more than one instance of the main landmark.

HTML 5 vs. ARIA:

As a general rule, it is usually best to use native HTML elements rather than their ARIA equivalents whenever possible. Therefore, even though the ARIA Role role="main" is listed among landmarks by most screen readers, its corresponding HTML5 element <main> should be used instead.
