更改 Bootstrap 導航鏈接顏色

Question

我正在嘗試將 Bootstrap 的導航鏈接更改為白色，但我不能。 這是我的代碼。

<nav class="navbar navbar-light" style="background-color: #5E9DFE;">
    <a class="navbar-brand" href="/"><span class="yellow">Div</span><span class="plate">Aid</span> <span class="salmon">T</span><span class="green">asks</span></a>
    <button aria-controls="navbar" aria-expanded="false" aria-label="Toggle navigation" class="navbar-toggler" data-target="#navbar" data-toggle="collapse" type="button">
        <span class="navbar-toggler-icon"></span>
    </button>
    <div class="collapse navbar-collapse" id="navbar">
        {% if session.user_id %}
             <ul class="navbar-nav mr-auto mt-2" id="add-del">
                 <li class="nav-item"><a class="nav-link" href="/add">Agregar</a></li>
                 <li class="nav-item"><a class="nav-link" href="/delete">Eliminar</a></li>
             </ul>
             <ul class="navbar-nav ml-auto mt-2">
                 <li class="nav-item"><a class="nav-link" href="/logout">Cerrar sesión</a></li>
             </ul>
        {% else %}
             <ul class="navbar-nav mr-auto mt-2" id="log-reg">
                  <li class="nav-item"><a class="nav-link" href="/register">Registro</a></li>
                  <li class="nav-item"><a class="nav-link" href="/login">Iniciar Sesión</a></li>
             </ul>
        {% endif %}
   </div>
</nav>

在看到以前的答案和CSS 特異性文檔后，我嘗試更改它：

nav .navbar-nav mr-auto mt-2 .nav-item .navlink{
    color: #ffffff;
}

nav .navbar-nav mr-auto mt-2 .nav-item .navlink:hover{
    color: #e8e8e8;
}

但仍然缺少一些東西。 我感謝您的幫助。

 .nav-link { color: red; } .nav-link:hover { color: green; }

 <nav class="navbar navbar-light" style="background-color: #5E9DFE;"> <a class="navbar-brand" href="/"><span class="yellow">Div</span><span class="plate">Aid</span> <span class="salmon">T</span><span class="green">asks</span></a> <button aria-controls="navbar" aria-expanded="false" aria-label="Toggle navigation" class="navbar-toggler" data-target="#navbar" data-toggle="collapse" type="button"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="navbar"> {% if session.user_id %} <ul class="navbar-nav mr-auto mt-2" id="add-del"> <li class="nav-item"><a class="nav-link" href="/add">Agregar</a></li> <li class="nav-item"><a class="nav-link" href="/delete">Eliminar</a></li> </ul> <ul class="navbar-nav ml-auto mt-2"> <li class="nav-item"><a class="nav-link" href="/logout">Cerrar sesión</a></li> </ul> {% else %} <ul class="navbar-nav mr-auto mt-2" id="log-reg"> <li class="nav-item"><a class="nav-link" href="/register">Registro</a></li> <li class="nav-item"><a class="nav-link" href="/login">Iniciar Sesión</a></li> </ul> {% endif %} </div> </nav>

Answer 2

你的 css 嵌套是錯誤的

嘗試這個：

nav .navbar-nav.mr-auto.mt-2 .nav-item .nav-link{
    color: #ffffff;
}

如果這不能解決問題，請嘗試添加!Important以粉碎預定義的引導程序樣式

nav .navbar-nav.mr-auto.mt-2 .nav-item .nav-link{
    color: #ffffff !important;
}

您可以簡單地將導航鏈接類中的 CSS 設置為白色

.nav-link {color: white;}
