Details

Rule ID Landmark 1
Definition Each page must have at least one main landmark, used to identify the main content.
Purpose
  • A main landmark provides a navigation point to the primary content of the page for users of assistive technologies.
  • Most pages only need one main landmark, but in the case of portals or mashups, there may be more than one main landmark on a "page".

Target Resources [role="main"] and main element
  • main
Techniques
  • A main element or an element with a role="main" attribute defines a main landmark.
  • When there is only one main landmark on the page (the typical case), do not use a label.
  • When there is more than one main landmark, use the aria-labelledby or aria-label attribute to describe the content of each.
  • If you need to support Microsoft Internet Explorer 8, you must NOT use the main element since the element is supported in the accessibility API, just use role="main" to identify the main landmark.

Column Definitions

Element Identifier
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.
Element Position
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.
