简单实用的Bootstrap选项卡效果

这是一款基于Bootstrap的简单实用的选项卡效果。该选项卡在原生boostrap选项卡的基础上进行了一些美化，效果时尚大方，非常不错。

使用方法

在页面中引入jquery和bootstrap相关文件。

<script src="path/to/jquery.min.js"></script> 
<link href="path/to/bootstrap.min.css" rel="stylesheet">
<script src="path/to/bootstrap.min.js"></script>
                

HTML结构

该bootstrap选项卡的HTML结构如下：

<div class="container">
    <div class="row">
        <div class="col-lg-offset-3 col-lg-6">
            <div class="tab" role="tabpanel">
                <!-- Nav tabs -->
                <ul class="nav nav-tabs" role="tablist">
                    <li role="presentation" class="active"><a href="#Section1" aria-controls="home" role="tab" data-toggle="tab">Section 1</a></li>
                    <li role="presentation"><a href="#Section2" aria-controls="profile" role="tab" data-toggle="tab">Section 2</a></li>
                    <li role="presentation"><a href="#Section3" aria-controls="messages" role="tab" data-toggle="tab">Section 3</a></li>
