Review the labeling of 4 landmarks to ensure that, if any other landmarks of the same type exist on the page, each has a unique accessible name.
Multiple instances of landmarks with the same role must have unique accessible names.
Landmarks identify the regions of content on a page.
When a landmark does not have an author-defined accessible name, assistive technologies will use its ARIA role as an identifier.
When there is more than one landmark of the same type on the page (e.g., multiple navigation and/or region landmarks), additional labeling through the use of author-defined accessible names is needed to allow users to differentiate among them.
Use the aria-labelledby attribute to provide a unique accessible name by referencing the id of a heading or other element on the page that describes the content of the landmark.
Use the aria-label attribute to provide a unique accessible name that describes the content of the landmark.
The title attribute may be used to provide a unique accessible name that describes the content of the landmark. Note, however, that many browsers will also generate a tooltip from the title attribute value.
While ARIA landmarks may be defined using the role attribute, some HTML5 sectioning elements have default landmark roles (e.g., main, nav, aside, and in some situations, header and footer). Thus when multiple nav elements, for example, are used on a page, define a unique accessible name for each of them.
Verify that the label describes the content of the landmark.
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.
