我正在使用Bootstrap3 <nav>
,在示例代码中,团队使用navbar-toggle collapsed
类在小屏幕上折叠导航栏中的元素。
我的问题是如何在折叠时更改它们的顺序? 我做了一个简短的片段:
<html>
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://code.jquery.com/jquery-3.2.1.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<nav class="navbar navbar-default">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target=".nav" aria-expanded="false">
<span class="sr-only">Options</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<ul class="nav navbar-nav collapse navbar-collapse">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Page 1</a></li>
<li><a href="#">Page 2</a></li>
</ul>
<div class="navbar-header">
<a class="navbar-brand" href="#">
<img alt="BRAND" src="some/img.png">
</a>
</div>
<ul class="nav navbar-nav navbar-right collapse navbar-collapse">
<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>
</nav>
</body>
</html>
为了澄清,在我的<nav>
中,从左到右有一个列表,一个图像,另一个列表。当它们在小屏幕上折叠时,顺序将从上到下,列表,图像和列表。折叠后如何将图像置于顶部?

最简单的方法是创建品牌html两次,并在xs上显示一个,在xs上隐藏另一个。
您可以通过将visible-xs
和hidden-xs
类添加到要在折叠导航栏时显示或隐藏的容器来执行此操作。
通过这样做,您可以在两个地方显示品牌形象,而无需添加任何JavaScript。
