Plain meaning

Navbars and Navs is a Bootstrap pattern for one practical job. Learn the input, apply the smallest working syntax, check the output, then reuse the pattern in a real feature.

Why it matters

Navbars and Navs matters because real Bootstrap work needs consistent ways to toggle drawer on smaller views. Without this pattern, the feature becomes harder to change, test and review.

  </div>
</nav>
