BootStrap实用代码片段(持续总结)

> 如题,持续总结自己在使用BootStrap中遇到的问题,并记录解决方法。希望能帮到需要的小伙伴

  1. 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%; }

实现效果:
