Question

我已经被困在这里很长一段时间了。搜索并尝试了多种方法来删除BS4汉堡包图标的边框颜色（在我的本地，它显示为黄色。在这个片段中，它是蓝色的）

有人可以帮忙解决这个问题吗？感谢帮助！

这是我的代码：

＆＃13;

<nav class="navbar sticky-top navbar-expand-lg" style="background-color: #eeeeee">
  <button class="navbar-toggler ml-auto hidden-sm-up float-xs-right" type="button" data-toggle="collapse" data-target="#navbarToggler" aria-controls="navbarToggler" aria-expanded="false" aria-label="Toggle navigation">
    <span><i class="fa fa-navicon"></i></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarToggler">
    <ul class="navbar-nav ml-auto mt-2 mt-lg-0">
      <li class="nav-item active">
        <a class="nav-link active" routerLink="/about" routerLinkActive="active">
          <span>About</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/projects" routerLinkActive="active">
          <span>Projects</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/contact" routerLinkActive="active">
          <span>Contact</span>
        </a>
      </li>
    </ul>
  </div>
</nav>

Answer 1

这在Bootstrap 4中对我有用。

  .navbar-toggler:focus, .navbar-toggler:active {
    outline: none;
    box-shadow: none;
  }

Answer 2

单击Bootstrap导航栏图标的汉堡图标时更改或删除边框颜色。您需要进入bootstrap.min.css文件并转到button:focus课程。在那里更改或完全删除outline。像这样：

button:focus {

outline: 1px dotted;
outline: 5px auto -webkit-focusring-color;

}

Answer 3

对于Bootstrap来说，他们不使用边框来使用大纲

的导航focus

你可以删除它宽度：

button.navbar-toggler.ml-auto.hidden-sm-up.float-xs-right:focus {
    outline: none!important;
}

希望这个帮助：＆gt;

button.navbar-toggler.ml-auto.hidden-sm-up.float-xs-right:focus {
    outline: none!important;
}

<nav class="navbar sticky-top navbar-expand-lg" style="background-color: #eeeeee">
  <button class="navbar-toggler ml-auto hidden-sm-up float-xs-right" type="button" data-toggle="collapse" data-target="#navbarToggler" aria-controls="navbarToggler" aria-expanded="false" aria-label="Toggle navigation">
    <span><i class="fa fa-navicon"></i></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarToggler">
    <ul class="navbar-nav ml-auto mt-2 mt-lg-0">
      <li class="nav-item active">

          <span>About</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/projects" routerLinkActive="active">
          <span>Projects</span>
        </a>
      </li>
      <li class="nav-item">
        <a class="nav-link" routerLink="/contact" routerLinkActive="active">
