我有以下代码,如果我将这两个导航栏保持为静态,这似乎有效:
<html>
<head>
<link href="./static/css/bootstrap.css" rel="stylesheet" media="screen">
<link href="./static/css/main.css" rel="stylesheet">
<link href="./static/css/bootstrap-responsive.css" rel="stylesheet">
</head>
<body >
<div class="bothnavbars">
<nav class="navbar navbar-default navbar-static-top nav1" role="navigation">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="container-fluid">
<div class="navbar-header ">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"></span> Name</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Sub menu link1</a></li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- ./container-fluid -->
</nav>
<nav class="navbar navbar-default navbar-static-top nav2" role="navigation">
<!-- Brand and toggle get grouped for better mobile display -->
<div class="container-fluid">
<div class="navbar-header ">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-2">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#"> Name</a>
</div>
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-2">
<ul class="nav navbar-nav">
<li class="active"><a href="#">Sub menu link1</a></li>
</ul>
</div><!-- /.navbar-collapse -->
</div><!-- ./container-fluid -->
</nav>
</div>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script src="./static/js/bootstrap.min.js"></script>
<div class="blockcontent">
Content
</div>
</body>
</html>
我在main.css中添加的CSS是:
.nav1 {
margin-bottom:10;
}
.nav2 {
top:0;
}
.blockcontent{
padding-top: 180px;
}
现在,如果我想将两个导航栏固定在顶部,我会更改
<nav class="navbar navbar-default navbar-static-top nav1" role="navigation">
到
<nav class="navbar navbar-default navbar-fixed-top nav1" role="navigation">
nav2相同。我将nav2类更改为
.nav2 {
top:60;
}
现在页面看起来不错,但是当我缩小浏览器大小并单击按钮查看菜单时,第一个导航栏无法正常运行。任何想法如何解决这个问题?
答案 0 :(得分:2)
您遇到的问题是navbar-fixed-top
将left
和right
位置都声明为0,因此实际上第二个导航与第一个导航重叠,因为它占据了整个屏幕宽度
要解决此问题,请添加以下代码:
<强> HTML 强>
<div class="bothnavbars">
<div class="navbar navbar-default navbar-fixed-top nav1">
<div class="navbar-header"><a class="navbar-brand" href="#">Brand</a></div>
<ul class="nav navbar-nav">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Link</a></li>
<li><a href="#">More</a></li>
<li><a href="#">Options</a></li>
</ul>
</div>
<div class="navbar navbar-default navbar-fixed-top nav2">
<div class="navbar-header"><a class="navbar-brand" href="#">Brand</a></div>
<ul class="nav navbar-nav">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Link</a></li>
<li><a href="#">More</a></li>
<li><a href="#">Options</a></li>
</ul>
</div>
</div>
<div class="blockcontent">
Content
</div>
和CSS:
.nav1 {
position:fixed; top:60; width:50%; left:0; right:50% !important
}
.nav2 {
position:fixed; top:60; right:0; width:50%; left:50% !important
}
我已经更改了您的HTML代码,因为它也有错误,因此我添加了一些易于查看的HTML,以便您可以看到它的工作方式并根据需要进行替换,您可以看到Bootply sample here
对于导航堆叠一个,将给定的CSS更改为:
/* CSS used here will be applied after bootstrap.css */
.nav1 {
position:fixed; top:0;
}
.nav2 {
position:fixed; top:50px; background:#fc0
}
@media handheld, only screen and (max-width: 767px) {
.nav1, .nav2{position:relative; top:0}
.nav2{top:-20px;}
}
请参阅Bootply(注意:为了可视化目的添加了背景颜色,但当然不需要)
