You'll remember that we have not brought over the precompiled CSS files from Bootstrap, nor have we yet compiled CSS from our LESS files. We'll do the latter shortly. But first, let's put at least one Bootstrap-specific element in place, that is, the navbar.

Initially, we want only Bootstrap's basic navbar (we'll add other details later). I've used the markup taken from Bootstrap's documentation and adjusted it in the following ways:

The preceding adjustments lead to the following result, nested with our header element:

<header role="banner">
  <nav role="navigation" class="navbar navbar-static-top navbar-default">
    <div class="container">
      <div class="navbar-header">
        <a class="navbar-brand" href="index.html">Project name</a>
      </div>
      <ul class="nav navbar-nav">
        <li class="active"><a href="index.html">Home</a></li>
        <li><a href="#">Link</a></li>
        <li><a href="#">Link</a></li>
      </ul>
    </div>
  </nav>
</header>

Save your results, and open or refresh index.html in your browser. You'll note that we don't have much yet, as shown in the following screenshot:

We have content. Now, we desperately need our stylesheet to come to the rescue. Let's compile and link up Bootstrap's default styles.
