You could get the width of the navbar to go the full length of the page by making the container inherit from ".navbar-wrapper". You may also want to get rid of the padding you have set in ".navbar-wrapper .navbar"
通过使容器从“.navbar-wrapper”继承，您可以使导航栏的宽度达到页面的全长。您可能还想摆脱在“.navbar-wrapper .navbar”中设置的填充
The following styles worked for me: See codpen: http://codepen.io/JordanLittell/pen/wadWxv
以下样式对我有用：请参阅 codpen：http://codepen.io/JordanLittell/pen/wadWxv
/* Special class on .container surrounding .navbar, used for positioning it into place. */
/* 围绕 .navbar 的 .container 上的特殊类，用于将其定位到位。*/
.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;
width: inherit;
}
.navbar-wrapper .navbar {
width: 100% !important;
}
.navbar-inverse {
width: 100% !important;
background-color: rgba(0, 0, 0, 0.5) !important;
border-radius: 0;
}
.navbar-inverse .nav > li > a {
color: #FFFFFF;
}
.navbar-inverse .nav > li > a:hover {
background: none;
}
.navbar-brand a {

Seems you are using .containerclass instead of container-fluidclass. As per bootstrap documentation:
似乎您正在使用.container类而不是container-fluid类。根据引导程序文档：
Turn any fixed-width grid layout into a full-width layout by changing your outermost
.containerto.container-fluid.
通过将最外层更改
.container为.container-fluid.

You should use the class container-fluidinstead of container.
您应该使用类container-fluid而不是container.
containerhas predefined width values for the different screen sizes (xs, sm, md, lg)container-fluidfills the available width
container具有针对不同屏幕尺寸（xs、sm、md、lg）的预定义宽度值container-fluid填充可用宽度
Also container's have some padding applied, and generally they are used in conjunction with row's that have the inverse margin.
还container的具有施加一些填充，并且通常它们被配合使用，row“具有逆余量秒。
So if you want full-widthyou either have to wrap your navbar in a row (inside your container) or you just don't use container's at all.
因此，如果您想要全角，则必须将导航栏排成一行（在容器内），或者根本不使用container's。
