Document should not have more than one main landmark
What is the problem?
The "landmark-no-duplicate-main" rule ensures that there is only one primary landmark on a page. This landmark, typically a main element, guides screen reader users to the main content.
Impacted Groups
Why is this important?
Multiple main landmarks can confuse screen reader users, making it difficult for them to understand the page structure and find the most important content. This can hinder their ability to navigate the page efficiently and access the information they need.
How to solve this issue
To fix this, ensure that there is only one main element on the page to designate the primary content. If you have iframes, each iframe should have at most one landmark to avoid confusion for screen reader users.
