This is one of my newest gists

nav_bootstrap5.html

<nav class="navbar navbar-expand-md bg-primary navbar-dark text-uppercase">
  <div class="container">
    <button
      type="button"
      class="navbar-toggler"
      data-bs-toggle="collapse"
      data-bs-target="#myTogglerNav"
      aria-controls="myTogglerNav"
      aria-label="Toggle Navigation"
    >
      <span class="navbar-toggler-icon"></span>
    </button>

    <a class="navbar-brand" href="#page-hero"><a class="navbar-brand" href="index.html">Layout</a>
    <div class="collapse navbar-collapse" id="myTogglerNav">
      <div class="navbar-nav ms-auto font-weight-regular">
        <a class="nav-item nav-link text-white" href="index.html">home</a>
        <a class="nav-item nav-link" href="columns.html">columns</a>
        <a class="nav-item nav-link" href="media.html">media</a>
      </div>
    </div>
  </div>
</nav>

This is a pretty simple example of a bootstrap 5 navigation.
