應用樣式表

Question

我有這個引導 html 代碼

 <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" rel="stylesheet"/> <nav class="navbar navbar-expand-sm navbar-light"> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarTogglerDemo03" aria-controls="navbarTogglerDemo03" aria-expanded="false" aria-label="Toggle navigation"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbarTogglerDemo03"> <ul class="navbar-nav mr-auto mt-2 mt-lg-0"> <li class="nav-item"> <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href="#">About</a> </li> <li class="nav-item dropdown dmenu"> <a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown"> Our Service </a> <div class="dropdown-menu sm-menu"> <a class="dropdown-item" href="#">service2</a> <a class="dropdown-item" href="#">service 2</a> <a class="dropdown-item" href="#">service 3</a> </div> </li> <li class="nav-item"> <a class="nav-link" href="#">Contact Us</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Call</a> </li> <!-- <li class="nav-item dropdown dmenu"> <a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown"> Dropdown link </a> <div class="dropdown-menu sm-menu"> <a class="dropdown-item" href="#">Link 1</a> <a class="dropdown-item" href="#">Link 2</a> <a class="dropdown-item" href="#">Link 3</a> <a class="dropdown-item" href="#">Link 4</a> <a class="dropdown-item" href="#">Link 5</a> <a class="dropdown-item" href="#">Link 6</a> </div> </li> --> </ul> <div class="social-part"> <i class="fa fa-facebook" aria-hidden="true"></i> <i class="fa fa-twitter" aria-hidden="true"></i> <i class="fa fa-instagram" aria-hidden="true"></i> </div> </div> </nav>

我想在下面的行中添加樣式表，使文本“Home”看起來是白色的。 請幫忙。

<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>

請幫我在上面的行中應用樣式表，使測試看起來是白色的。 我需要在此應用白色。

添加您的主頁文本燈。 我將背景更改為深色，以便可以看到家
