Html 在 Bootstrap 3.3.2 中更改导航栏断点

Change Navbar breakpoint in Bootstrap 3.3.2

提问by Matt Hall

I'm putting together a rough navbar using Twitter bootstrap.

我正在使用 Twitter 引导程序组合一个粗略的导航栏。

There's a breakpoint at which the width of the device will cause the navbar items to collapse and show a menu button instead:

有一个断点，设备的宽度将导致导航栏项目折叠并显示菜单按钮：

How can I change the breakpoint so the navbar collapses sooner? At the moment its able to break on to a new line when it comes up against the logo, which doesn't look too great:

如何更改断点以便导航栏更快地折叠？目前它能够在遇到标志时换行，这看起来不太好：

I've tried a fix detailed here, but it seemed to break the collapsed menu (couldn't expand it again afterwards).

我已经尝试了一个详细的修复here，但它似乎打破了折叠菜单（之后无法再次展开它）。

Here's the html:

这是html：

    <!-- navigation -->
    <div class="navbar navbar-default navbar-static-top">
        <div class="container-fluid">
            <div class="navbar-header">

                <button class="navbar-toggle" data-toggle="collapse" data-target=".navbar-responsive-collapse">

Which version of bootstrap are you using? 3.1? Anyway, I need as well your css to help you to fix it, but generally:

您使用的是哪个版本的引导程序？3.1？无论如何，我也需要你的 css 来帮助你修复它，但通常：

@media (max-width: 1200px) {
    .navbar-header {
        float: none;
    }
    .navbar-left,.navbar-right {
        float: none !important;
    }
    .navbar-toggle {
        display: block;
    }
    .navbar-collapse {
        border-top: 1px solid transparent;
        box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
    }
    .navbar-fixed-top {
        top: 0;
        border-width: 0 0 1px;
    }
    .navbar-collapse.collapse {
        display: none!important;
    }
    .navbar-nav {
        float: none!important;
        margin-top: 7.5px;
    }
    .navbar-nav>li {
        float: none;
    }
    .navbar-nav>li>a {
        padding-top: 10px;
        padding-bottom: 10px;
    }
    .collapse.in{
        display:block !important;
    }
   .navbar-nav .open .dropdown-menu {
       position: static;
       float: none;
       width: auto;
       margin-top: 0;
       background-color: transparent;
       border: 0;
       -webkit-box-shadow: none;
       box-shadow: none;
    }
}

The max width is the breakpoint. Copied from Bootply(with demo included there).

最大宽度是断点。从Bootply复制（其中包含演示）。

The following code will create a navbar breakpoint at 991 px. The .navbar-nav class is important if you have more than a few links in your navbar.

以下代码将在 991 像素处创建一个导航栏断点。如果您的导航栏中有多个链接，.navbar-nav 类很重要。

@media (max-width: 991px) {
  .navbar-header {
      float: none;
  }
  .navbar-left,.navbar-right {
      float: none !important;
  }
  .navbar-toggle {
      display: block;
  }
  .navbar-collapse {
      border-top: 1px solid transparent;
      box-shadow: inset 0 1px 0 rgba(255,255,255,0.1);
  }
  .navbar-fixed-top {
      top: 0;
      border-width: 0 0 1px;
  }
  .navbar-collapse.collapse {
      display: none!important;
  }
  .navbar-nav {
      float: none!important;
      margin-top: 7.5px;

      max-height: 300px;
      overflow-y: scroll!important;
  }
  .navbar-nav>li {
      float: none;
  }
  .navbar-nav>li>a {
      padding-top: 10px;
      padding-bottom: 10px;
  }
  .collapse.in{
      display:block !important;
  }

}
