bootstrap 折叠菜单

首先从 左侧的折叠菜单 开始。看图。

2. CSS 代码

以下是自定义的css代码，由于系统是内部使用，所以优先考虑chrome,firefox 不考虑IE了。

		#main-nav {
			margin-left: 1px;
		}

			#main-nav.nav-tabs.nav-stacked > li > a {
				padding: 10px 8px;
				font-size: 12px;
				font-weight: 600;
				color: #4A515B;
				background: #E9E9E9;
				background: -moz-linear-gradient(top, #FAFAFA 0%, #E9E9E9 100%);
				background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#FAFAFA), color-stop(100%,#E9E9E9));
				background: -webkit-linear-gradient(top, #FAFAFA 0%,#E9E9E9 100%);
				background: -o-linear-gradient(top, #FAFAFA 0%,#E9E9E9 100%);
				background: -ms-linear-gradient(top, #FAFAFA 0%,#E9E9E9 100%);
				background: linear-gradient(top, #FAFAFA 0%,#E9E9E9 100%);
				filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#FAFAFA', endColorstr='#E9E9E9');
				-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#FAFAFA', endColorstr='#E9E9E9')";
				border: 1px solid #D5D5D5;
				border-radius: 4px;
			}

				#main-nav.nav-tabs.nav-stacked > li > a > span {
					color: #4A515B;
				}

				#main-nav.nav-tabs.nav-stacked > li.active > a, #main-nav.nav-tabs.nav-stacked > li > a:hover {
					color: #FFF;
					background: #3C4049;
					background: -moz-linear-gradient(top, #4A515B 0%, #3C4049 100%);
					background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#4A515B), color-stop(100%,#3C4049));
					background: -webkit-linear-gradient(top, #4A515B 0%,#3C4049 100%);
					background: -o-linear-gradient(top, #4A515B 0%,#3C4049 100%);
					background: -ms-linear-gradient(top, #4A515B 0%,#3C4049 100%);
					background: linear-gradient(top, #4A515B 0%,#3C4049 100%);
					filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#4A515B', endColorstr='#3C4049');
					-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#4A515B', endColorstr='#3C4049')";
					border-color: #2B2E33;
				}

					#main-nav.nav-tabs.nav-stacked > li.active > a, #main-nav.nav-tabs.nav-stacked > li > a:hover > span {
						color: #FFF;
					}

			#main-nav.nav-tabs.nav-stacked > li {
				margin-bottom: 4px;
			}

		/*定义二级菜单样式*/
		.secondmenu a {
			font-size: 10px;
			color: #4A515B;
			text-align: center;
		}

		.navbar-static-top {
			background-color: #212121;
			margin-bottom: 5px;
		}

		.navbar-brand {
			background: url('') no-repeat 10px 8px;
			display: inline-block;
			vertical-align: middle;
			padding-left: 50px;
			color: #fff;
		}

3. HTML 代码

HTML代码比较简单。 data-toggle http://v3.bootcss.com/components/ 这里有介绍。

<div class="navbar navbar-duomi navbar-static-top" role="navigation">
		<div class="container-fluid">
			<div class="navbar-header">
				<a class="navbar-brand" href="/Admin/index.html" id="logo">配置管理系统（流量包月）
				</a>
			</div>
		</div>
	</div>
	<div class="container-fluid">
		<div class="row">
			<div class="col-md-2">
				<ul id="main-nav" class="nav nav-tabs nav-stacked" style="">
					<li class="active">
						<a href="#">
							<i class="glyphicon glyphicon-th-large"></i>

					</li>

				</ul>
			</div>
			<div class="col-md-10">
				主窗口

		</div>
	</div>

4. 引用的css 和 js
