Bootstrap导航栏透明 [英] Bootstrap navbar transparent

问题描述

出于某种原因，我无法让导航栏更改。我试图让它透明。我知道bootstrap导航栏通常是一个图像，所以我包括 background-image：none 。

For some reason I cannot get the navbar to change. I tried to make it transparent. I know bootstrap navbar is normally an image so I included background-image: none.

<nav class="navbar navbar-inverse navbar-fixed-top">
  <div class="container-fluid">
    <div class="navbar-header page-scroll">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
        <span class="sr-only">Toggle navigation</span>
      </button>
    <a class="navbar-brand page-scroll" href="#intro">Eric West</a>
  </div>
  <div class="collapse navbar-collapse navbar-ex1-collapse">
    <ul class="nav navbar-nav">
        <li class="hidden">
          <a class="page-scroll" href="#page-top"></a>
        </li>
        <li>
          <a class="page-scroll" href="#about">About</a>
        </li>
      </ul>
      <ul class="nav navbar-nav navbar-right">
        <li>
          <a class="page-scroll" href="#projects">Projects</a>
        </li>
        <li>
          <a class="page-scroll" href="#contact">Contact</a>
        </li>
      </ul>
    </div>
  </div>
</nav>

推荐答案

不要移除.navbar （或.navbar-default），除非你计划添加一些自定义CSS来弥补它，因为这些添加属性到导航，特别是导航栏切换

Don't remove .navbar-inverse (or .navbar-default) unless you plan on adding some custom CSS to make up for it because these add properties to the nav, in particular to the navbar-toggle class.

如果没有其中一个，您将从您的导航中删除大量CSS，并且 navbar-toggle 将会在768px以下的设备上不可见，它将在那里并可操作，但您将无法看到它。

Without one of those you'll remove alot of CSS from your nav and the navbar-toggle will not be visible on a device under 768px, it will be there and actionable but you won't be able to see it.

我会添加自定义导航类并使用这是为了覆盖你需要更改的属性。

I would add a custom nav class and use that to override the property you need to change.

查看示例，其中包含一个没有附加属性的示例。

See example with that includes one with and one without the additional property.

body,
html {
  background: grey;
  margin-top: 50px;
}
.navbar.navbar-custom {
  background-color: transparent;
}
