Question

 <nav class="navbar-toggleable-sm" role="navigation">
      <div class="container justify-content-center">


          <div class="navbar-brand navbar-brand-centered">Brand</div>




          <ul class=" navbar-nav float-left">
            <li class = "nav-item"><a class=" nav-link" href="#">Link</a></li>
            <li class = "nav-item"><a  class=" nav-link" href="#">Link</a></li>
            <li class = "nav-item"><a class=" nav-link"  href="#">Link</a></li>
          </ul>
          <ul class=" navbar-nav float-right">
            <li class = "nav-item"><a class=" nav-link" href="#">Link</a></li>
            <li class = "nav-item"><a class=" nav-link" href="#">Link</a></li>
            <li class = "nav-item"><a class=" nav-link" href="#">Link</a></li>              
          </ul>
        <!-- /.navbar-collapse -->
      </div><!-- /.container-fluid -->
    </nav>

我已经开始在这里学习bootsrap 4我希望我的导航就像前三个链接到左侧，其他链接到我的品牌标识右侧，整个容器也被称为中心。
