twitter-bootstrap – Twitter Bootstrap 3增加navbar-header div宽度

<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header" >
      <button type="button" class="navbar-toggle" 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>
        <span class="icon-bar"></span>
      </button>
      <a class="navbar-brand" href="#">Company</a>

        <form class="navbar-form navbar-left" role="search">
            <div class="form-group">
                <input type="text" class="form-control" placeholder="Search">
            </div>
        </form>
    </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 navbar-right">
        <li><a href="#/Activity">Activity</a></li>
        <li class="active"><a href="#/Customers">Customers</a></li>
        <li><a href="#/Inventory">Inventory</a></li>
        <li><a href="#/orders">orders</a></li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->

基本上,我一直在搜索Twitter Bootstrap 3和Stack-Overflow过去2-3小时.

我想增加div类navbar-header的宽度,以便我可以有一个跨越导航栏顶部中间的搜索输入.

似乎当导航栏崩溃时它将搜索扩展到太远.

Example in Fiddle

基本上我想要与Gmail相同的东西,包括谷歌徽标,大搜索框,右侧的图标/链接.
