我正在看这个bootply：http://www.bootply.com/mQh8DyRfWY#
崩溃在bootply上运行正常，但在我的项目中我无法切换它。这是我的HTML：

这是我的CSS：
.browsehappy {
margin: 0.2em 0;
background: #ccc;
color: #000;
padding: 0.2em 0;
}
body {
padding: 0;
}
/* Everything but the jumbotron gets side spacing for mobile first views */
.header,
.marketing,
.footer {
padding-left: 15px;
padding-right: 15px;
}
/* Custom page header */
.header {
border-bottom: 1px solid #e5e5e5;
margin-bottom: 10px;
}
.navbar-brand
{
position: absolute;
width: 100%;
left: 0;
top: 0;
text-align: center;
margin: auto;
}
/* Make the masthead heading the same height as the navigation */
.header h3 {
margin-top: 0;
margin-bottom: 0;
line-height: 40px;
padding-bottom: 19px;
}
/* Custom page footer */
.footer {
padding-top: 19px;
color: #777;
border-top: 1px solid #e5e5e5;
}
.container-narrow > hr {
margin: 30px 0;
}
/* Main marketing message and sign up button */
.jumbotron {
text-align: center;
border-bottom: 1px solid #e5e5e5;
}
.jumbotron .btn {
font-size: 21px;
padding: 14px 24px;
}
/* Supporting marketing content */
.marketing {
margin: 40px 0;
}
.marketing p + h4 {
margin-top: 28px;
}
/* Responsive: Portrait tablets and up */
@media screen and (min-width: 768px) {
.container {
max-width: 730px;
}
/* Remove the padding we set earlier */
.header,
.marketing,
.footer {
padding-left: 0;
padding-right: 0;
}
/* Space out the masthead */
.header {
margin-bottom: 30px;
}
/* Remove the bottom border on the jumbotron for visual effect */
.jumbotron {
border-bottom: 0;
}
}
如果我删除.navbar-brand的css，那么它工作正常但看起来不正确。
请告知如何继续。谢谢

你navbar-brand覆盖你的切换按钮，因为它设置为100％宽度。见工作示例。
.browsehappy {
margin: 0.2em 0;
background: #ccc;
color: #000;
padding: 0.2em 0;
}
body {
padding: 0;
}
/* Everything but the jumbotron gets side spacing for mobile first views */
.header,
.marketing,
.footer {
padding-left: 15px;
padding-right: 15px;
}
/* Custom page header */
.header {
border-bottom: 1px solid #e5e5e5;
margin-bottom: 10px;
}
.navbar-brand.navbar-brand-centered {
position: absolute;
left: 50%;
display: block;
width: 200px;
text-align: center;
top: 0;
}
.navbar > .container .navbar-brand.navbar-brand-centered,
.navbar > .container-fluid .navbar-brand.navbar-brand-centered {
margin-left: -100px;
}
/* Make the masthead heading the same height as the navigation */
.header h3 {
margin-top: 0;
margin-bottom: 0;
line-height: 40px;
padding-bottom: 19px;
}
/* Custom page footer */
.footer {
padding-top: 19px;
color: #777;
border-top: 1px solid #e5e5e5;
}
.container-narrow > hr {
margin: 30px 0;
}
/* Main marketing message and sign up button */
.jumbotron {
text-align: center;
border-bottom: 1px solid #e5e5e5;
}
.jumbotron .btn {
font-size: 21px;
padding: 14px 24px;
}
/* Supporting marketing content */
.marketing {
margin: 40px 0;
}
.marketing p + h4 {
margin-top: 28px;
}
/* Responsive: Portrait tablets and up */
@media screen and (min-width: 768px) {
.container {
max-width: 730px;
}
/* Remove the padding we set earlier */
.header,
.marketing,
.footer {
padding-left: 0;
padding-right: 0;
}
/* Space out the masthead */
.header {
margin-bottom: 30px;
}
/* Remove the bottom border on the jumbotron for visual effect */
.jumbotron {
border-bottom: 0;
