在下面的代码中，当单击折叠菜单时，会给出一个与页面全宽的下拉菜单。
<div class="row">
<div class="col-sm-8">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar-collapse">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<!-- navbar-header -->
<nav class="collapse navbar-collapse navigation" id="navbar-collapse">
<ul class="nav navbar-nav menu">
<li><a href="/">Home</a></li>
<li><a href="features.html">Features</a></li>
<li><a href="lifestyle.html">Lifestyle</a></li>
<li><a href="travel.html">Travel</a></li>
<li><a href="music.html">Music</a></li>
<li><a href="about.html">About</a></li>
<li><a href="contact.html">Contact Me</a></li>
</ul>
</nav>
</div>
<!-- navbar-collapse -->
<div class="col-sm-4 navigation" id="social-icons">
<ul class="menu">
<a href=""><i class="fa fa-facebook"></i></a>
<a href=""><i class="fa fa-twitter"></i></a>
<a href=""><i class="fa fa-instagram"></i></a>
<a href=""><i class="fa fa-pinterest"></i></a>
<a href=""><i class="fa fa-heart"></i></a>
<a href=""><i class="fa fa-google-plus"></i></a>
<a href=""><i class="fa fa-tumblr"></i></a>
</ul>
</div>
<!-- social-icons -->
</div>
<!-- row -->
</div>
<!-- container -->
</nav>
是否有任何方法可以减少下拉菜单的宽度，使其两侧有一些空白空间？
编辑: 这是我想要实现的目标的图像。

最佳答案
还有另一种方法可以使用 css 来做到这一点，我刚刚添加了这些类
.navbar-inverse { background-color:transparent; }
#navbar-collapse {
background: #222 ;
float: left;
width:100%;
}
.navbar-inverse::after {
background: #222 none repeat scroll 0 0;
content: "";
height: 50px;
position: absolute;
top: 0;
width: 100%;
z-index: -1;
}
.navbar-inverse { background-color:transparent; border-color:transparent; }
