这是cs，我已经编写了css，我尝试了stackoverflow类似问题中其他类似问题的代码。

我不知道媒体查询的位置是错误的还是没用的。

提前致谢....

Answer 1

使用以下 css 代码并根据需要提供值。这将为折叠菜单提供断点。

已更新。 我为每个地方添加了一个额外的类 .navigatsioon 。然后就成功了

@media (max-width: 1024px) {
  .navigatsioon ul.nav.navbar-nav {
    margin-left: -15px;
  }
  .navigatsioon .navbar-header {
    float: none;
  }
  .navigatsioon .navbar-left,
  .navbar-right {
    float: none !important;
  }
  .navigatsioon .navbar-toggle {
    display: block;
  }
  .navigatsioon .navbar-collapse {
    border-top: 1px solid transparent;
    box-shadow: inset 0 1px 0 rgba(255, 255, 255, 0.1);
  }
  .navigatsioon .navbar-fixed-top {
    top: 0;
    border-width: 0 0 1px;
  }
  .navigatsioon .navbar-collapse.collapse {
    display: none!important;
  }
  .navigatsioon .navbar-nav {
    float: none!important;
    margin-top: 7.5px;
  }
  .navigatsioon .navbar-nav>li {
    float: none;
  }
  .navigatsioon .navbar-nav>li>a {
    padding-top: 10px;
    padding-bottom: 10px;
  }
  .navigatsioon .collapse.in {
    display: block !important;
  }
}

.navbar-nav.navbar-center {
    position: absolute;
    left: 45%;
    transform: translatex(-45%);
}

.navbar .navbar-brand {
  padding-top: 5px;
  padding-left:150px;
}
