Bootstrap - nav tag

HTML-CSS

Why aren’t the navigation elements displayed horizontally instead of vertically? Here is the code:

<header class="container">
  <div class="row">
    <h1 class="col-sm-4">Skillfare</h1>
    <nav class="col-sm-8 text-right">
      <p>newest</p>
      <p>catalogue</p>
      <p>contact</p>
    </nav>
  </div>
</header>

thank you…i tried making them links and they are displayed in one line…

<header class="container">
  <div class="row">
    <h1 class="col-sm-4">Skillfare</h1>
    <nav class="col-sm-8 text-right">
      <a href="#">newest</a>
      <a href="#">catalogue</a>
      <a href="#">contact</a>
    </nav>
  </div>
</header>
