当屏幕尺寸小于481像素时,我试图改变div位置, 我在滑块后几乎在页面中间导航但在移动视图中它需要在滑块上方,这就是我尝试做的事情
<style type="text/css">
.navPosition{position: relative;top: 0 !important;margin-bottom: 100px;}
</style>
<script src="js/bootstrap.js" type="text/javascript"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-alpha1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$width=$(window).width();
if($width<481){
$("#navbg").addClass("navPosition");
}
});
</script>
这是我的导航代码
<nav class="navbar" role="navigation" id="navbg">
<div class="container-fluid">
<!-- Brand and toggle get grouped for better mobile display -->
切换导航
<!-- Collect the nav links, forms, and other content for toggling -->
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav home-nav">
<li> <a href="#">Home</a></li>
<li> <a href="#">About us</a></li>
<li> <a href="#">Academics</a></li>
<li> <a href="#">News & Events</a></li>
<li> <a href="#">Contact us</a></li>
</ul>
</div>
<!-- /.navbar-collapse -->
</div>
<!-- /.container -->
</nav>
但这对我不起作用,我是如何完成它的,请求帮助

尝试使用媒体查询来执行此操作
div#demo {
position: relative;
margin-top:10px;
}
@media only screen and (max-width: 481px) {
div#demo{
margin-top:200px;
}
}
并在html端创建具有该ID的div
<div id='demo'> This is the demo for media query</div>
我为你创建了一个小jsfiddle
