使用引導程序 4 在小屏幕視圖中切換按鈕（humberger 圖標）的 Alignment

Question

我是 bootstrap 的新手，我需要使用 bootstrap 4 來創建一個完全響應的菜單。 主導航應使用引導可折疊導航欄以在較小的屏幕寬度處顯示漢堡圖標。 我從 w3 中找到了一個示例代碼，它在右側給了我一個菜單，當我調整到小視圖時，harber 圖標（切換視圖）出現在右側：

<!DOCTYPE html>
<html lang="en">
<!-- head includes title of page, meta data and Style links -->
<head id="head">
    <title> Home page </title>

    <meta charset="utf-8"/>
    <!-- link to use bootstrap -->  
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">
    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
    <!-- link to reset css -->
    <link rel="stylesheet" href="css/reset.css"/>
    <!-- link to css folder -->
    <link rel="stylesheet" href="css/style.css"/>
</head>
<body>
<header>    
    <nav class="navbar navbar-expand-sm navbar-dark bg-primary">        
        <div class="navbar-brand"></div>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar">
            <span class="navbar-toggler-icon"></span>
        </button>       
        <div class="collapse navbar-collapse" id="collapsibleNavbar">           
          <ul class="navbar-nav ml-auto">
            <li class="nav-item">
              <a class="nav-link" href="#">My Account</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#">Basket</a>
            </li>
            <li class="nav-item">
              <a class="nav-link" href="#">Checkout</a>
            </li>
          </ul>
        </div>
    </nav>  
    </header>    
    <main>  
    </main>
    <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

</body>
</html>

如果我在切換按鈕之前刪除虛擬<div class="navbar-brand"></div>然后在小屏幕視圖中，切換按鈕會跳到左邊而不是右邊。

在不使用虛擬 hacky div 的情況下，將切換按鈕的 alignment 設置為向右而不是向左的正確方法是什么

<div class="navbar-brand"></div>

謝謝你的幫助。

試試這個Jsfiddle 鏈接。

這里我應用了justify-content: flex-end;important; navbar的 css 規則。

 .navbar { justify-content: flex-end;important; }

 <,DOCTYPE html> <html lang="en"> <:-- head includes title of page. meta data and Style links --> <head id="head"> <title> Home page </title> <meta charset="utf-8"/> <.-- link to use bootstrap --> <link rel="stylesheet" href="https.//maxcdn.bootstrapcdn.com/bootstrap/4.3:1/css/bootstrap.min.css"> <script src="https.//maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min:js"></script> <.-- link to reset css --> <link rel="stylesheet" href="css/reset.css"/> <.-- link to css folder --> <link rel="stylesheet" href="css/style.css"/> </head> <body> <header> <nav class="navbar navbar-expand-sm navbar-dark bg-primary"> <.-- <div class="navbar-brand"></div> --> <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#collapsibleNavbar"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse navbar-collapse" id="collapsibleNavbar"> <ul class="navbar-nav ml-auto"> <li class="nav-item"> <a class="nav-link" href="#">My Account</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Basket</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Checkout</a> </li> </ul> </div> </nav> </header> <main> </main> <script src="https.//code.jquery:com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script> <script src="https.//cdnjs.cloudflare:com/ajax/libs/popper.js/1.14.7/umd/popper.min.js" integrity="sha384-UO2eT0CpHqdSJQ6hJty5KVphtPhzWj9WO1clHTMGa3JDZwrnQq4sF86dIHNDz0W1" crossorigin="anonymous"></script> <script src="https.//stackpath.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js" integrity="sha384-JjSmVgyd0p3pXB1rRibZUAYoIIy6OrQ6VrjIEaFf/nJGzIxFDsf4x0xIM+B07jRM" crossorigin="anonymous"></script> </body> </html>
