Question

我无法更改切换图标栏的颜色。我想将颜色更改为白色。

MySQL Workbench 6.3

的style.css

下面是我的css文件：

<nav class="navbar navbar-toggleable-md navbar-light">
    <button class="navbar-toggler navbar-toggler-right" type="button"  style = "border: 2px solid #E0E0E0;" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon icon-bar" style = "color: white;"></span>
    </button>
    <a class="navbar-brand" href="#">SWAPNIL SARAF</a>
    <div class="collapse navbar-collapse" id="navbarNav">
        <ul class="navbar-nav ml-auto">
            <li class="nav-item active">
            <a class="nav-link" href="#">WORK <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item">
            <a class="nav-link" href="#">INSPIRATIONS</a>
            </li>
            <li class="nav-item">
            <a class="nav-link" href="#">ABOUT</a>
            </li>
            <li class="nav-item">
            <a class="nav-link" href="#">CONTACT</a>
            </li>
        </ul>
    </div>
</nav>

Answer 1

我检查了您的代码结构以及您的css代码无效的原因，因为 .navbar-toggle 类已从按钮代码中删除，如下所示：

 <button class=" navbar-toggler  navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">

所以在这里添加类 navbar-toggle ，因为bootstrap css是在这个类的基础上编写的。

   <button class=" navbar-toggle navbar-toggler  navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">

另请查看我尝试使用您的html代码的示例：

.navbar .navbar-toggler .icon-bar {
  background: black !important;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="http://netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>

<nav class="navbar navbar-toggleable-md navbar-light">
  <button class="navbar-toggle navbar-toggler  navbar-toggler-right" type="button" style="border: 2px solid #E0E0E0;" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon icon-bar" ></span>
            </button>
  <a class="navbar-brand" href="#">SWAPNIL SARAF</a>
  <div class="collapse navbar-collapse" id="navbarNav">
    <ul class="navbar-nav ml-auto">
      <li class="nav-item active">
        <a class="nav-link" href="#">WORK <span class="sr-only">(current)</span></a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">INSPIRATIONS</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">ABOUT</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="#">CONTACT</a>
      </li>
    </ul>
  </div>
</nav>

Answer 2

我在这里注意到两个问题

在style.css

将！importtant替换为！important

像这样使用css类

.navbar-toggler-icon.icon杆{ background-color：white！important; }

谢谢，阿伦

Answer 3

试试这个

.navbar-default .navbar-toggle .icon-bar {
        background-color: #ffffff !important;
    }

Answer 4

将其更改为您的代码。

<强> HTML

<span class="navbar-toggler-icon icon-bar"></span>

<强> CSS

.navbar .navbar-toggler .icon-bar {
    color: #fff !important;
}

Answer 5

我已将颜色更改为红色。试试这个，你可以改变你想要的颜色

＆＃13;

  .navbar-inverse .navbar-toggle .icon-bar {
    background-color: red !important;
}

Answer 6

首先，您需要准确了解特定版本的Bootstrap中icon-bar的特定CSS选择器路径。我发现最可靠的方法是使用Developer Tools控制台。例如，在Chrome中，右键单击图标并选择inspect。

这会让您大致了解html中icon-bar跨度的位置，您应该看到类似.navbar-default .navbar-toggle .icon-bar的内容，其中包含一个background-color规则，如下面的屏幕截图所示。< / p>

COOL TIP：您可以点击background-color规则的小颜色框直接在页面上更改icon-bar颜色。

从那里开始，应该只是简单地从开发工具窗口中复制CSS，将其粘贴到自定义CSS文件中并调整颜色。

希望有所帮助！
