The “Inappropriate Banner Landmark Check” evaluates whether the banner landmark is nested in another region’s landmark.
Example outcome
I noticed that the banner landmark is contained within other landmark.
Impact
Visual Impairments: Screen reader users may not recognize or access the banner as expected. It could be skipped or misinterpreted.
Motor Impairments: Improper structure can interrupt keyboard-only navigation, increasing the number of actions needed to reach site-wide navigation or branding.
Cognitive Disabilities: Incorrect landmark nesting can lead to confusion and poor page comprehension.
Fixes
To address banner landmarks inappropriately contained within other landmarks:
Locate the inappropriately placed banner landmark.
Removing it from the other landmark region, and place it on top of the page.
