Axe Core 4.6

All page content should be contained by landmarks

The recommended practice is to keep all content, excluding skip links, in designated areas such the header, nav, main, and footer.

If the content is divided into several high-level divisions, screen reader users can navigate a website much more easily. Finding content that isn’t in parts can be challenging, and the item’s intent sometimes isn’t evident.

Some essential semantic markers, such as the ability to designate portions of the page as the header, navigation, primary content, and footer, were formerly absent from HTML. It is recommended to combine HTML5 elements with ARIA landmarks in a single element, but as browser support for HTML5 grows, using native HTML5 element regions will become more common.
