No main landmark
FAIL — this page has no <main> element. axe-core: landmark-one-main (moderate best practice)
This entire page is a content area that sits outside any landmark region. The page header, this section, and the content below are all uncontained by <main>, <section aria-label>, or any other landmark.
Content outside landmarks
FAIL — this content is not wrapped in any landmark region. axe-core: region (moderate best practice)
For comparison, on the Compliant page all content is wrapped in <main id="main-content"> and section elements with aria-labelledby. Here nothing is wrapped, which means screen reader users cannot navigate by landmark.
There is also a second block of content here, also outside any landmark. Both blocks will contribute to the "region" violation count.
What a correct structure looks like
INFO — for reference only (this demo is still non-compliant at page level)
A compliant page uses: <main> for the primary content, <nav> for navigation (which this page does have), <footer> for the footer, and <section aria-labelledby="..."> for named content regions.
