使用引導程序更改導航欄的字體顏色

Question

我一直在嘗試覆蓋導航欄的字體顏色，但似乎無法弄清楚。 我想要背景顏色為橙色，而字體顏色為白色。

導航欄的HTML：

<nav class="navbar navbar-expand-lg navbar-light bg-light">
   <a class="navbar-brand" href="#">Rocalytics</a>
   <button class="navbar-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 mr-auto">
         <li class="nav-item active">
            <a class="nav-link" href="#">Value Proposition</a>
         </li>
         <li class="nav-item dropdown active">
            <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true"
               aria-expanded="false">
            Dropdown
            </a>
            <div class="dropdown-menu" aria-labelledby="navbarDropdown">
               <a class="dropdown-item" href="#">Scheduling</a>
               <div class="dropdown-divider"></div>
               <a class="dropdown-item" href="#">Contact Management</a>
               <div class="dropdown-divider"></div>
               <a class="dropdown-item" href="#">Analytics</a>
            </div>
         </li>
         <li class="nav-item active">
            <a class="nav-link" href="#">User Experience</a>
         </li>
         <li class="nav-item active">
            <a class="nav-link" href="#">Contact Us</a>
         </li>
      </ul>
      <form class="form-inline my-2 my-lg-0">
         <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Sign Up</button>
      </form>
   </div>
</nav>

CSS：

/* NAVBAR */
.navbar {
  background-color: #f78c20 !important;
  color: white !important;
}

背景顏色設法改變，字體顏色沒有改變。 我也試圖避免使用!important 。 有什么建議么？

您可以將類添加到更具體的標簽，例如nav-link ， dropdown-item

 /* NAVBAR */ .navbar { background-color: #f78c20 !important; color: white; } .nav-link, .dropdown-item { color: white; } 

 <nav class="navbar navbar-expand-lg navbar-light bg-light"> <a class="navbar-brand" href="#">Rocalytics</a> <button class="navbar-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 mr-auto"> <li class="nav-item active"> <a class="nav-link" href="#">Value Proposition</a> </li> <li class="nav-item dropdown active"> <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> Dropdown </a> <div class="dropdown-menu" aria-labelledby="navbarDropdown"> <a class="dropdown-item" href="#">Scheduling</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="#">Contact Management</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="#">Analytics</a> </div> </li> <li class="nav-item active"> <a class="nav-link" href="#">User Experience</a> </li> <li class="nav-item active"> <a class="nav-link" href="#">Contact Us</a> </li> </ul> <form class="form-inline my-2 my-lg-0"> <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Sign Up</button> </form> </div> </nav>
