我正在看这个 bootply:http://www.bootply.com/mQh8DyRfWY#

折叠在 bootply 上运行良好，但在我的元素中我无法切换它。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，它可以正常工作，但看起来不正确。

请告知如何进行。谢谢

最佳答案

您 navbar-brand 覆盖了您的切换按钮，因为它设置为 100% 宽度。查看工作示例。

.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;
  }
