How to fix landmark unique on Webflow

Steps for Webflow

1. Open your project in the Webflow Designer.
2. Click on the Navbar, Section, or other repeated landmark element on the canvas.
3. In the right-side Element Settings panel (the gear icon), scroll down to the 'Custom Attributes' section.
4. Click the '+' icon to add a new attribute. Set the Name to aria-label and the Value to a unique, descriptive label (e.g. 'Main navigation').
5. Repeat for every other instance of the same landmark type on the page, giving each a distinct label (e.g. 'Footer navigation' for the second <nav>).
6. Publish the site, then verify with the axe DevTools browser extension on the live URL.

What is landmark unique?

Landmarks are special HTML regions — like `<nav>`, `<main>`, `<header>`, `<footer>`, `<aside>`, and `<section>` — that act as signposts for people using screen readers or keyboard-only navigation. When the same type of landmark appears more than once on a page (for example, two `<nav>` menus or two `<section>` blocks), each one must carry a unique label so users can understand what each region contains and jump directly to the right one. Without these labels, a screen reader will just announce "navigation" twice, with no way to tell which is which.

Screen-reader users rely on landmark navigation to skip around a page quickly — it's the equivalent of sighted users scanning headings at a glance. Duplicate, unlabeled landmarks force these users to listen through entire sections just to find what they need, creating a frustrating, unusable experience. This violates WCAG 2.1 Success Criterion 1.3.6 (Identify Purpose) and is flagged by automated accessibility checkers like axe. Depending on your market, failing WCAG 2.1 AA exposes your business to legal risk under the ADA (US), the European Accessibility Act (EU), and similar laws. Beyond compliance, accessible stores convert better — a broader audience can browse and buy without barriers.
