Question

Bootstrap 4的新功能，我正在尝试使用以下标记构建响应式导航栏：

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">
	<title>Test Website</title>
    <link rel="stylesheet" href="/styles/style.css">    
</head>
<body>	
	<!-- Navigation Bar -->
	<nav class="navbar navbar-expand-md navbar-dark bg-primary sticky-top">
		<a class="navbar-brand" href="tel:8005551212">Call Us At (800) 555-1212 For An Appointment</a>
		<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="navResponsive">
			<span class="navbar-toggler-icon"></span>
		</button>
		<div class="collapse navbar-collapse" id="navResponsive">
			<ul class="navbar-nav ml-auto">

我遇到的问题是菜单文本包装的浏览器大小调整。有没有办法避免这种情况？

此外，如果单击切换菜单，则不会显示下拉列表。我错过了什么吗？

Answer 1

data-target你需要它#以便将切换分配到菜单并且你分配了ID，它必须是

data-target="#navResponsive"

对于文本换行问题，您只需进行max-width

.navbar .navbar-brand {
    max-width: 80%;
    white-space: normal;
}

＆＃13;

.navbar .navbar-brand {
    max-width: 80%;
    white-space: normal;
}

＆＃13;
