     <div class="container-fluid"> 
      <!-- Brand and toggle get grouped for better mobile display --> 
      <div class="navbar-header"> 
       <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> 
        <span class="sr-only">Toggle Navigation</span> 
        <span class="icon-bar"></span> 
        <span class="icon-bar"></span>

        <img id="brand-image" alt="Website Logo" src="Images/a.png" /> 
       </a> 
      </div> 
      <!-- Collect the nav links, forms, and other content for toggling --> 
      <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
       <ul class="nav navbar-nav"> 
        <li class="active"><a href="#">Home<span class="sr-only">(current)</span></a></li> 
        <li><a href="#">About Us</a></li> 
        <li class="dropdown"> 
         <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Classes <span class="caret"></span></a> 
         <ul class="dropdown-menu" role="menu"> 
          <li><a href="#">1</a></li> 
          <li><a href="#">2</a></li> 
          <li><a href="#">3</a></li> 
         </ul> 
        </li> 
       </ul> 

       <form class="navbar-form navbar-right" role="search"> 
      <a href=""><i class="fa fa-facebook fa-2x"></i></a> 
      <a href=""><i class="fa fa-instagram fa-2x"></i></a> 
       </form> 


      </div><!-- navbar collapse end --> 
     </div><!-- container-fluid end --> 
    </nav> 

CSS：

.navbar-default .navbar-collapse, .navbar-default .navbar-form { 
    min-height: 175px;

    min-height: 175px; 
} 

Answer 1

1日加入text-align: center;导航栏容器bs-example-navbar-collapse-1这样子元素将对齐到中心，

2日为UL，将其设置为display: inline-block;所以它不会采取全行（块）

从引导CSS 3 ，.navbar-nav设置为float: left覆盖它使用float: none !important;

此外，如果你试图让搜索栏的工作，看看这个，也许：https://jsfiddle.net/dalinhuang/nmtnkjx5/

#bs-example-navbar-collapse-1 { 
 
    text-align: center; 
 
} 
 

 
.navbar-nav { 
 
    float: none !important; 
 
} 
 

 
#bs-example-navbar-collapse-1>ul { 
 
    display: inline-block; 
 
}
