How to fix landmark main is top level on Webflow

Steps for Webflow

1. In the Webflow Designer, open the page or the site's global layout.
2. In the Navigator panel (left sidebar), find the element that has the 'Main' tag or has 'role=main' set — typically a Section or Div element labeled 'Main Wrapper' or similar.
3. Check its parent element in the Navigator. If the parent is a 'Header' element, a Nav, or any other landmark-tagged container, drag the Main element out so it is a direct child of the Body node in the Navigator.
4. To set or verify the HTML tag: select the element → go to Element Settings (D key) → HTML Tag → choose 'main'.
5. Ensure the Header and Footer elements are siblings of Main, not parents.
6. Publish the site and verify with axe DevTools or WAVE in your browser.

What is landmark main is top level?

Every webpage should have exactly one "main" landmark — the HTML `<main>` tag or any element with `role="main"` — that tells assistive technologies like screen readers "this is where the primary content begins." The WCAG rule `landmark-main-is-top-level` fires when that `<main>` landmark is accidentally placed inside another landmark element (such as `<header>`, `<nav>`, `<section>`, `<aside>`, or `<footer>`) instead of being a direct child of `<body>`. Think of landmarks like a building's floor plan: the "main hall" should open directly off the entrance, not be hidden inside a closet inside a side room.

Screen-reader users rely on landmark navigation to jump straight to the main content, skipping repetitive menus and headers — a fundamental assistive-technology workflow. When `<main>` is buried inside another landmark, screen readers mis-report the page structure, the "skip to content" shortcut may stop working, and keyboard-only users are forced to tab through every navigation item on every page. This directly harms the browsing experience for customers with disabilities and exposes your store to legal risk under laws tied to WCAG 2.1 compliance (ADA in the US, EN 301 549 in the EU, AODA in Canada, and equivalents worldwide). Fixing it is also a positive signal for Google's accessibility-aware ranking considerations and demonstrates a technically well-structured page to crawlers.
