Spacing with the Menu

Question

I am the following problem:

I can’t get that spacing off the menu with Jumbotron.

<nav class="navbar navbar-inverse navbar-fixed-top">
      <div class="container">
        <div class="navbar-header">
          <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="nav$">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </button>
          <a class="navbar-brand" href="sucesso.php">BW</a>
        </div>
        <div id="navbar" class="collapse navbar-collapse">
          <ul class="nav navbar-nav">
            <li class="#"><a href="sucesso.php">Home</a></li>
            <li><a href="#">Perguntas</a></li>
            <li><a href="perfil.php">Perfil</a></li>
          </ul>
        </div><!--/.nav-collapse -->
      </div>
</nav>

 <div class="jumbotron">   
   <div class="container">
         
                <h1>Bem vindo!</h1>
                <p>Agora você já pode tirar suas dúvidas.</p>
                <p><a class="btn btn-primary btn-lg" href="#" role="button">Fazer pergunta</a></p>
            </div>
        </div>
