bootstrap 4 导航活动链接颜色

Question

我想将活动菜单链接的颜色更改为绿色。我尝试了各种方法（查看开发者模式从框架中应用了哪些规则），但没有奏效。你能建议如何进行吗？我正在使用 Bootstrap 4 和 mdbootstrap。

HTML代码：

  <nav class="navbar navbar-expand-md navbar-light sticky-top">

    <div id="navcontainer" class="d-flex container py-2 justify-content-center align-items-center">

<!-- Logo+Nev -->
      <div id="nevtitulus" class="d-flex align-items-start mr-lg-5 mr-md-3">
        <div>
          <img id="logo" class="mr-lg-3 mr-2" src="images/DRLJ_logo.png" alt="logo">
        </div>
        <!--logo-->
          <div class="text-center">
            <span id="logoname">Dr. Langmár Judit</span>
            <!-- hide on screens smaller than md -->
            <p id="logodesc" class="d-none d-md-block">Akupunkt?r, üzemorvos, orthopaed szakorvos</p>
            <!-- hide on screens wider than sm -->
            <p id="logodesc2" class="d-md-none">Akupunkt?r, üzemorvos, <br> orthopaed szakorvos</p>
          </div>
          <!--Nev+titulus-->
      </div> <!--logo+nev container-->

    <div id="hamburger-wrapper" class="ml-5 ml-md-0">

      <div id="button-wrapper" class="d-flex szelesseg justify-content-center">
<!-- hamburger menu -->
        <button class="navbar-toggler" type="button"
            data-toggle="collapse" data-target="#navcollapse" aria-controls="navcollapse"
            aria-expanded="false" aria-label="Toggle Navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
      </div>
<!-- collapse navbar -->
        <div class="collapse navbar-collapse" id="navcollapse">
          <ul class="nav navbar-nav text-center">
            <li class="nav-item"><a class="nav-link" href="#fooldal">F?oldal<span class="sr-only">(current)</span></a></li>
            <li class="nav-item"><a class="nav-link" href="#kezelesek">Kezelések</a></li>
            <li class="nav-item"><a class="nav-link" href="#arak">Árak</a></li>
            <li class="nav-item"><a class="nav-link" href="#galeria">Galéria</a></li>
            <li class="nav-item"><a class="nav-link" href="#rolam">Rólam</a></li>
            <li class="nav-item"><a class="nav-link" href="#kapcsolat">Kapcsolat</a></li>
          </ul>
        </div>
        <!-- collapse navbar -->
      </div>
      <!--hamburger-wrapper-->
    </div>
    <!--Navcontainer-->
    </nav>

到目前为止我尝试过的 CSS 技巧，但没有奏效（只有悬停有效）：

.navbar.navbar-light .navbar-nav .nav-item .nav-link:hover {
color: rgb(129, 91, 73);
background-color: rgba(0, 0, 0, 0.1);
}

.navbar-light .navbar-nav .nav-item .nav-link:focus {
  color: #0DB159;
}

.navbar-light .navbar-nav .nav-item:active .nav-link {
  color: #0DB159;
}

#navcollapse a:active {
    color: #0DB159;
}

下面的这个有效，但前提是导航所指的锚标记从正文中删除

.nav.navbar-nav .nav-item .nav-link:focus {
  color: #0DB159
}

我也试过这些，但直到锚标签在身体里才起作用......

.nav.navbar-nav .nav-item .nav-link:focus,
.nav.navbar-nav .nav-item:focus,
.nav.navbar-nav .nav-item a:focus,
.nav.navbar-nav .nav-item .nav-link a:focus,
.nav.navbar-nav .nav-item .nav-link:active,
.nav.navbar-nav .nav-item:active,
.nav.navbar-nav .nav-item a:active,
.nav.navbar-nav .nav-item .nav-link a:active {
  color: #1c8a66}

我的朋友建议在 CSS 中使用 .active 类，但这也不起作用：

    .nav.navbar-nav .nav-item .nav-link.active {
      color: #1c8a66
   }

HTML 中的锚点：

<a class="anchor" id="kezelesek"></a>

CSS 中的锚点类

a.anchor {
    display: block;
    position: relative;
    top: -57px;
    visibility: hidden;
}

在这里你可以看到问题：如果相应的anchor标签存在，菜单不会改变颜色：

Answer 1

您需要使用与 Bootstrap CSS 选择器具有相同特性的 CSS 选择器。

.navbar-light .nav-item.active .nav-link,
.navbar-light .nav-item .nav-link:active,
.navbar-light .nav-item .nav-link:focus,
.navbar-light .nav-item:hover .nav-link {
    color: #00B159;
}
