# Use exactly one main landmark

A single main landmark allows keyboard and screen reader users to jump directly to the primary content of the page, bypassing repetitive navigation.

## Quick Reference

- Ensure each page has exactly one `<main>` element
- Avoid multiple elements with `role='main'`
- Provides a clear starting point for the page's primary content

## Check

Count the number of <main> elements or elements with role='main' on the page to ensure there is exactly one.
