折叠导航栏

标签: html css navbar bootstrap-grid

我创造了一个完美无缺的navbar,但是当菜单折叠时,它看起来像是一条神秘的黑线(见黄色箭头),它在汉堡下面运行。任何帮助删除这将非常感激。

上面是我的HTML和CSS。过去有人遇到过这个吗?

使用.navbar-inverse时,默认颜色会变暗。请参阅反向导航类型的链接。

Link: Inverse Nav Bar with background color

你的错误是,你正在定义没有bg的逆向导航 - 如link所示。

请使用以下

,而不是反向
<nav class="navbar navbar-light" style="background-color: #fb4f14;">
  <!-- Navbar content -->
</nav>

您将获得#fb4f14的预期导航背景作为背景颜色。但最简单的解决方案是,只要您想要自定义背景颜色,就可以使用其他类型的导航而不是navbar-inverse

你的黑线并不神秘,因为当你没有为逆定义任何bg颜色时,inverse会将默认颜色设置为黑暗颜色。请参阅反向导航示例:

<nav class="navbar navbar-inverse "> <!-- default dark black line --->
  <!-- Navbar content -->
</nav>

<nav class="navbar navbar-inverse bg-primary"> <!-- primary color matched border line --->
  <!-- Navbar content -->
</nav>
