Bootstrap每天必学之响应式导航、轮播图

本节课前一节我们开始设计第一个项目， 一个内训公司的企业网站， 本节课学习响应式导航部分。

基本导航组件+响应式：

//基本导航组件+响应式
<nav class="navbar navbar-default navbar-fixed-top">
<div class="container">
<div class="navbar-header">
<a href="#" class="navbar-brand"
style="margin:0;padding:0;"><img src="img/logo.png" alt="瓢城企训网"></a>
<button type="button" class="navbar-toggle"
data-toggle="collapse" data-target="#navbar-collapse">
<span class="sr-only">切换导航</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
</div>
<div class="collapse navbar-collapse" id="navbar-collapse">
<ul class="nav navbar-nav navbar-right"
style="margin-top:0;">
<li class="active">
<a href="#"><span class="glyphiconglyphicon-home"></span> 首页</a>
</li>
<li>
<a href="#"><span class="glyphicon
glyphicon-list"></span> 资讯</a>
</li>
<li>
<a href="#"><span class="glyphicon
glyphicon-fire"></span> 案例</a>
</li>
<li>
<a href="#"><span class="glyphicon
glyphicon-question-sign"></span> 关于</a>
</li>
</ul>
</div>
</div>
</nav>

后一节我们要在导航条的下方做一张轮播图，自动播放最新的重要动态。

//响应式轮播图
<div id="myCarousel" class="carousel slide">
<ol class="carousel-indicators">
<li data-target="#myCarousel" data-slide-to="0"
class="active"></li>
<li data-target="#myCarousel" data-slide-to="1"></li>
<li data-target="#myCarousel" data-slide-to="2"></li>
</ol>
<div class="carousel-inner">
<div class="item active" style="background:#223240;">
<a href="#"><img src="img/slide1.png" alt="第一张"></a>
</div>
<div class="item" style="background:#F5E4DC;">
<a href="#"><img src="img/slide2.png" alt="第二张"></a>
</div>
<div class="item" style="background:#DE2A2D;">
<a href="#"><img src="img/slide3.png" alt="第三张"></a>
</div>
</div>
<a href="#myCarousel" data-slide="prev" class="carousel-controlleft">&lsaquo;</a>
<a href="#myCarousel" data-slide="next" class="carousel-controlright">&rsaquo;</a>
</div>

//所需要的 jQuery 控制
$('#myCarousel').carousel({
//设置自动播放/2 秒
interval : 3000,
});
//调整轮播器箭头位置
$('.carousel-control').css('line-height', $('.carousel-innerimg').height() + 'px');
$(window).resize(function() {
var $height = $('.carousel-inner img').eq(0).height() || $('.carousel-inner img').eq(1).height() || $('.carousel-inner img').eq(2).height();
$('.carousel-control').css('line-height', $height + 'px');
});

//所需要的 CSS
a:focus {
outline: none;
}
.navbar-brand {
padding: 0;
}
#myCarousel {
margin: 50px 0 0 0;
}
.carousel-inner .item img {
margin: 0 auto;
}
.carousel-control {
font-size: 100px;
}
