Bootstrap手機菜單按鈕不可見

Question

當我在手機視圖中顯示時，我無法查看bootstrap菜單的菜單按鈕。同時，我需要刪除Bootstrap提供的所有ui樣式並擁有自己的造型的導航欄。

<nav class="navbar-fixed-top" role="navigation"> 
    <div class="container-fluid"> 
    <div class="navbar-header"> 
     <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> 
     <span class="icon-bar"></span> 
     <span class="icon-bar"></span> 
     <span class="icon-bar"></span> 
     </button> 
     <a class="navbar-brand" href="#">WebSiteName</a> 
    </div> 
    <div class="collapse navbar-collapse" id="myNavbar"> 
     <ul class="nav navbar-nav"> 
     <li class="active"><a href="#">Home</a></li> 
     <li><a href="#">Page 1</a></li> 
     <li><a href="#">Page 2</a></li> 
     <li><a href="#">Page 3</a></li> 
     </ul> 
     <ul class="nav navbar-nav navbar-right"> 
     <li><a href="#"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li> 
     <li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a></li> 
     </ul> 
    </div> 
    </div> 
</nav> 

Answer 1

您應該添加導航欄導航欄默認或導航欄導航欄逆所以你的導航鏈接，按鈕等有顏色/狀態適用於他們。

<nav class="navbar navbar-default navbar-fixed-top" role="navigation"> 

如果你想透明或白色背景的CSS CSS。

隨着導航欄默認

<nav class="navbar navbar-default navbar-fixed-top" role="navigation"> 
 
    <div class="container-fluid"> 
 
    <div class="navbar-header"> 
 
     <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> 
 
     <span class="icon-bar"></span> 
 
     <span class="icon-bar"></span> 
 
     <span class="icon-bar"></span> 
 
     </button> 
 
     <a class="navbar-brand" href="#">WebSiteName</a> 
 
    </div> 
 
    <div class="collapse navbar-collapse" id="myNavbar"> 
 
     <ul class="nav navbar-nav"> 
 
     <li class="active"><a href="#">Home</a> 
 
     </li> 
 
     <li><a href="#">Page 1</a> 
 
     </li> 
 
     <li><a href="#">Page 2</a> 
 
     </li> 
 
     <li><a href="#">Page 3</a> 
 
     </li> 
 
     </ul> 
 
     <ul class="nav navbar-nav navbar-right"> 
 
     <li><a href="#"><span class="glyphicon glyphicon-user"></span> Sign Up</a> 
 
     </li> 
 
     <li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Login</a> 
 
     </li> 
 
     </ul> 
 
    </div>

</nav>
