html – Bootstrap导航栏100％宽度不起作用

但我已尝试在.navbar-wrapper和navbar以及navbar-default上宽度100％.但由于某种原因,导航栏仍然不会达到页面的整个宽度.

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(0,0.5) !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;
}
