代碼如下：

  <!-- 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="#">Brand</a>
  </div>

生成效果：

求個方法可以更好的修改navbar-brand,，讓它居中而不是靠左,？

我是這么處理的：

CSS

@media (max-width: 768px){
	.navbar-header {
	    text-align: center;
	    width: 100%;
	}
	.navbar-brand {
		float:none;
	        display:inline-block;
	  	margin-left: auto;
	  	margin-right: auto;
	  	margin-top: 0;
	}
}
