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,我也试图在页面上进行完整操作.

但我已经尝试了宽度100%.navbar-wrapper和navbar和navbar-default,但由于某些原因,导航栏仍然不会去页的整个宽度.

问题如何使导航栏宽度100%工作,使其达到页面的整个宽度？

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>

</button>
<div class="navbar-brand">
<a href="#">Brand</a>

</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">

</ul>

Answer 1

看起来你正在使用.container类而不是container-fluid类.根据bootstrap文档:

通过改变你的最外圈任何固定宽度的网格布局成一个全宽度的布局.container来.container-fluid.

Answer 2

您可以通过使容器继承“.navbar-wrapper”来使导航栏的宽度达到页面的整个长度。您可能还想删除在“.navbar-wrapper .navbar”中设置的填充

以下样式对我有用：请参阅 codpen：http://codepen.io/JordanLittell/pen/wadWxv

/* .navbar 周围的 .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 {
    color: #FFFFFF;
}

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