这篇文章主要为大家详细介绍了BootStrap实用代码片段之一,总结在使用BootStrap中遇到的问题,并记录解决方法,感兴趣的小伙伴们可以参考一下
应用场景:经典上下布局中,顶部导航条固定,下部填充不显示滚动条
解决方案:导航条固定在顶部,同时为body设置内边距(padding-top),内边距为导航条高度(默认50px,可自己调整高度),html代码如下:
<!--html页面布局-->
<div class="container-fluid page-wrapper">
<!--导航栏-->
<div class="navbar navbar-default navbar-fixed-top" role="navigation">
<div class="container">
<!--logo图标-->
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#myMenu">
<span class="sr-only">切换导航条</span> <span class="icon-bar"></span>
<span class="icon-bar"></span> <span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="">
<img src="images/logo_2.png" alt="">
</a>
</div>
<!--导航栏菜单-->
<div class="collapse navbar-collapse" id="myMenu">
<ul class="nav navbar-nav">
<li>
<a href="index.html" style="">主页</a>
</li>
<li>
<a href="#" data-toggle="modal">河道站点</a>
</li>
<li>
<a href="#" data-toggle="modal">水库站点</a>
</li>
<li>
<a href="#">气象站点</a>
</li>
<li>
<a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">降雨量<span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li>
<a data-toggle="modal">1小时降雨</a>
</li>
<li>
<a href="#">3小时降雨</a>
</li>
<li>
<a href="#">24小时降雨</a>
</li>
</ul>
</li>
</ul>
<form class="navbar-form navbar-left" role="search">
<div class="form-group">
<input type="text" id="datetimepicker" class="form-control" placeholder="选择日期">
</div>
<button type="button" class="btn btn-default">确定</button>
</form>
</div>
</div>
</div>
<!--地图窗口-->
<div class="container-fluid" id="map"></div>
</div>
</body>
</html>
CSS代码:
*{
margin:0;
padding:0;
border:0;
}
html, body{
height:100%;
width:100%;
overflow:hidden;
}
body{
padding-top:50px;
}
.page-wrapper{
margin:0;
padding:0;
height:100%;
overflow:hidden;
}
#map{
width:100%;
height:100%;
}
