Let's use Bootstrap's grid to create a simple header with navbar.

In the example code below, an HTML header element with Bootstrap's predefined container class is used:

<header class="container">
  ...
</header>

Inside the header, a row is created by using a div with Bootstrap's row class:

<header class="container">
  <div class="row">
  </div> 
</header>

Finally, the row is cut into two parts:

<header class="container">
  <div class="row">
   <h1 class="col-sm-4">Heading</h1>
   <nav class="col-sm-8 text-right">
    <p>nav item 1</p>
    <p>nav item 2</p>
    <p>nav item 3</p>
   </nav> 
 </div>
</header>

The first part consists of the h1 with Bootstrap's class col-sm-4. It will take up the first four columns on the grid. The second part consists of the nav element with class col-sm-8. It will take up the remaining eight grid columns. text-right indicates that text will be arranged on the right side of the nav.
