html - Bootstrap 导航栏 100% 宽度不起作用

Question

在我的 bootstrap 导航栏上，即使导航栏位于图像顶部，我也试图在页面上显示完整内容。

但我已经在 .navbar-wrapper 和 navbar 和 navbar-default 上尝试了 width 100% 但由于某种原因，导航栏仍然会不会占满页面宽度。

实例

这是我的代码笔 Code View

这是我的代码笔 Full View

问题如何让我的导航栏宽度达到 100% 以达到整个页面的宽度？

CSS

/* Special class on .container surrounding .navbar, used for positioning it into place. */
.navbar-wrapper {
    position: absolute;
    top: 0;
    right: 0;
    width: 100% !important;
    left: 0;
    z-index: 20;
}

/* Flip around the padding for proper display in narrow viewports */
.navbar-wrapper > .container {
    padding-right: 0;
    padding-left: 0;
}

.navbar-wrapper .navbar {
    padding-right: 15px;
    padding-left: 15px;
    width: 100% !important;
}

.navbar-inverse {
  width: 100% !important;
    background-color: rgba(0, 0, 0, 0.5) !important;
}

.navbar-inverse .nav > li > a {
    color: #FFFFFF;
}

.navbar-inverse .nav > li > a:hover {
    background: none;
}

.navbar-brand a {
    color: #FFFFFF;
}

.main-header-background {
    background-size: 100% 100%;
    background-repeat: no-repeat;
    background-position: center; 
    background-image: url('./images/stars/img-stars-2.jpg');
    height: 620px;
    width: 100%;
    margin-bottom: 60px;
}

HTML

<div class="navbar-wrapper">
<div class="container">

<nav class="navbar navbar-inverse">
<!-- 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>
<span class="icon-bar"></span>
</button>
<div class="navbar-brand">
<a href="#">Brand</a>
</div>
</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="#">Link <span class="sr-only">(current)</span></a></li>
<li><a href="#">Link</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>

<li><a href="#">Separated link</a></li>
<li class="divider"></li>
<li><a href="#">One more separated link</a></li>
</ul>
</li>
</ul>

<ul class="nav navbar-nav navbar-right">
<li><a href="#">Link</a></li>
<li class="dropdown">
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Dropdown <span class="caret"></span></a>
<ul class="dropdown-menu" role="menu">

<li><a href="#">Something else here</a></li>
<li class="divider"></li>
<li><a href="#">Separated link</a></li>
</ul>
</li>
</ul>

</div><!-- /.navbar-collapse -->
</nav>

<div class="main-header-background">

似乎您正在使用 .container 类而不是 container-fluid 类。根据 Bootstrap 文档:

Turn any fixed-width grid layout into a full-width layout by changing your outermost .container to .container-fluid.
