Bootstrap Navbar宽度与容器相同

Question

我正在使用Bootstrap 3.我不能给导航栏带有与容器相同的宽度.如果它在大屏幕上工作,但不适用于其他屏幕尺寸.如何制作固定尺寸的导航栏,它将改变与容器宽度相同的不同屏幕.

<div class="row"><!--Start row-->
     <nav class="navbar navbar-default navbar-inverse navbar-fixed-top" role="navigation">
         <div class="container">
                <div class="navbar-header"><!-- -->
                    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#collapse">
                        <span class="sr-only">Toggle navigation</span>
                        <span class="glyphicon glyphicon-arrow-down">Menu</span>
                    </button>

                </div>
                <div class="collapse navbar-collapse" id="collapse">
                    <ul class="nav navbar-nav">
                        <li><a href="#">Home</a></li>
                        <li><a href="#">About</a></li>
                        <li><a href="#">Course List</a></li>
                        <li><a href="#">Contact Us</a></li>
                    </ul>
                </div><!--End Collapse-->
         </div>
     </nav><!--End Navbar-->
</div>

Answer 1

我要做的修复就是简单地将container类放在<nav class="...">这个中,将你的nave bar约束为container属性指定的宽度.

代码如下:

<nav class="navbar navbar-default navbar-inverse navbar-fixed-top container" role="navigation">
         <div class="container-fluid">
                <div class="navbar-header"><!-- -->
                    <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#collapse">
                        <span class="sr-only">Toggle navigation</span>
                        <span class="glyphicon glyphicon-arrow-down">Menu</span>
                    </button>

                </div>
                <div class="collapse navbar-collapse" id="collapse">
                    <ul class="nav navbar-nav">
                        <li><a href="#">Home</a></li>
                        <li><a href="#">About</a></li>
                        <li><a href="#">Course List</a></li>
                        <li><a href="#">Contact Us</a></li>
                    </ul>
                </div><!--End Collapse-->
         </div>
     </nav>

此外,<nav>包裹在一起并不是必要的,<div class="row">我希望这是你想要的.
