Question

我有一个带有链接的导航栏，我添加了活动类。为此活动类我添加了文本修饰css属性。我的问题是我想在文本和下划线之间添加间隙。我也使用border bottom属性，但是在屏幕尺寸小于992px，底线覆盖了整个div，我不是那个人。有人可以帮助我

HTML：

<nav class="navbar navbar-expand-lg navBgcolor fixed-top">
  <a class="navbar-brand hiddenDiv" href="#">Bootstrap</a>
  <button class="navbar-toggler custom-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>

  <div class="collapse navbar-collapse" id="navbarSupportedContent">
    <ul class="navbar-nav ml-auto">
      <li class="nav-item">
        <a class="nav-link active" href="index.html">HOME</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="application.html">JOIN OUR TEAM</a>
      </li>
      <li class="nav-item">
        <a class="nav-link" href="enrollment.html">ADMISSIONS</a>
      </li>
    </ul>
  </div>
</nav>

CSS：

<style>
  .navbar .nav-item > .nav-link.active {
    text-decoration: underline;
    text-decoration-color: #BB202E;
  }
</style>

您可以对:after菜单元素使用.active来尝试以下解决方案，以显示边框。使用top值，您可以调整文本和边框之间的间距：

.navbar .nav-item > .nav-link.active {
  display:inline-block;
  position:relative;
}

.navbar .nav-item > .nav-link.active:after {
  content: "";
  position: absolute;
  top: 80%;
  background: #BB202E;
  height: 2px;
  left:0;
  right:0;
}

@media (min-width: 992px) {
  .navbar .nav-item > .nav-link.active:after {
    left: .5rem;
    right: .5rem;
  }
}
