Document should have one main landmark
What is the problem?
The "landmark-one-main" rule ensures that a web page has one primary landmark, typically marked with the role="main" attribute. This landmark helps screen reader users quickly navigate to the main content of the page.
Impacted Groups
Why is this important?
For screen reader users, landmarks provide a high-level overview of a page's structure. Multiple main landmarks can confuse users and make it difficult to find the most important content.
How to solve this issue
To fix this, identify the primary content area on your page and apply the role="main" attribute to the appropriate HTML element. Ensure there's only one such element per page. If your page contains iframes, each should have either no landmarks or a single main landmark.
