What is this?

nav marks major navigation blocks — skip wrapping every link list in nav.

Why should you care?

MarkupVerse primary and footer sitemaps use nav with accessible names when multiple exist.

What happened?

  • aria-label when more than one nav.
  • Lists inside nav are a common pattern.
  • Don’t nav-wrap social icon rows without need.

Practice next

  1. Primary nav with ul.
  2. Footer nav with label.
  3. Tab the links.
  4. Add aria-current="page" on active link.
  5. Add skip link to #main.

Remember

Major nav only. Name multiples. Lists OK inside.

MarkupVerse dual nav

Primary + footer labeled.

Outcome: SR users pick the right landmark.
