Inappropriate Main Landmark Check

Description

The “Inappropriate Main Landmark Check” evaluates whether there is any main landmark nested within another region’s landmark.

Example outcome

I noticed that the main landmark is contained within other landmark.

Impact

• Visual Impairments: Screen readers may skip or misidentify the main content, making it harder to understand the page structure.
• Motor Impairments: Landmark navigation (like jumping to the main region using keyboard shortcuts) may not work as expected.
• Cognitive Disabilities: Users may struggle to understand where core content begins if structural cues are inconsistent.

Fixes

To address inappropriate main landmarks:

1. Locate the inappropriately placed main landmark.
2. Remove it from within the landmark in which it is nested.
