How to Fix the Problem
Ensure any contentinfo landmark is not be contained in another
landmark.
Text content should be contained within a landmark region, the
role="contentinfo" ARIA landmark should be used on an element
that is outside of other landmarks used on the page, since footer information
is generally separated from the header and main body content.
Why it Matters
The purpose of the contentinfo landmark can be defeated when
placed within another landmark, as it can prevent blind screen reader users
from being able to quickly find and navigate to the appropriate landmark.
When screen reader users have to sort through too much extra information to
find what they're looking for, such as not being able to quickly figure out
which landmark contains the content information they're looking for negates
the purpose of an existing contentinfo landmark.
Rule Description
Contentinfo landmark must be at top level.
The Algorithm (in simple terms)
This rule finds the elements for the footer:not([role]) and [role="contentinfo"] selectors, then checks to see if the landmark has a body context.
