Reserve the navigation landmark for website and page navigation links.
Website and page navigation links should be top-level navigation landmarks (i.e. not contained in other landmarks).
The nav element or an element with role="navigation" attribute defines a navigation landmark and must be on a container element (e.g., div) for ol and ul elements that contain li elements with links. (This may require adding a container element.)
If there is only one navigation landmark on the page, do not use a label.
If there is more than one navigation landmark, use the aria-labelledby, aria-label oe title attribute to describe the purpose of the links (e.g., Table of Contents, Site Map, etc.) contained in each.
If the same set of links is used in more than one place on a page, use "Copy 1", "Copy 2" ... "Copy N" as a part of the accessible name to make the navigation labels unique and help orient assistive technology users that the group of links is repeated on the page.
A list of links to other pages in the website, or to content sections of the current page, should use a navigation landmark.
Verify the links are used for website or page navigation purposes.
Verify the labels uniquely identify each set of navigational links.
Information about the element associated with the result.
The information typically includes the tag name, accessible name or other information related to the rule requirements.
"Page" means that the result applied to the page. For example, the rule "One main landmark on the page" is a page level rule.
The element position is based on the DOM order of elements in the page.
The element position maybe useful in helping to locate a specific element on the page evaluated (e.g smaller numbers are typically toward the beginning of a page and larger numbers typically toward the end of a page).
Element position 1 is the first element.
The highest element position is the last element.
Element position values for most rule/page results will not be consecutive since a rule only applies to a sub set of elements found on a page.
