Question

我试图将汉堡包菜单图标栏改为白色。但它没有改变。如何更改图标栏颜色？我认为它停留在默认颜色。

HTML

<nav class="navbar navbar-default navbar-fixed-top">
  <div class="container">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle collapsed" data-
        toggle="collapse" data-target="#myNavbar" aria-expanded="false" 
        aria-controls="navbar">

        <span class="sr-only">Toggle navigation</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>

      </button>
    <a class="navbar-brand" href="#myPage">WASHINGTOWN</a>
</div>
</div>
</nav>

CSS

navbar-default .navbar-toggle,
.navbar-default, span.icon-bar {
color: white !important;
}

Answer 2

.navbar-default .navbar-toggle .icon-bar

在您提供的CSS中，使用逗号分隔选择器，然后您的选择器不足以覆盖默认颜色。另外。确保您的CSS文件标签低于Bootstrap的标签。
