title: Putting content/banner above the "Fixed Top Navbar"
body: <p>I want to put an banner onto the <em>fixed top navbar</em> of the Bootstrap. My aim is using the navbar as the navigation for operations and putting a banner of the project above it. It will be cool if navbar is alway there in case of scrolling,  but it is better for banner to disappear.</p>
  
  <p>How can I achieve that, any examples?</p>
