这是一款炫酷Bootstrap美化Tabs选项卡特效。该选项卡特效基于Bootstrap原生Tab选项卡的基础上，使用CSS样式来进行美化，增加了tab标签的伸缩动画功能。

使用方法

子啊页面中引入bootstrap相关文件和fontawsome字体图标文件。

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

HTML结构

选项卡的基本HTML结构如下：

<div class="container">
    <div class="row">
        <div class="col-md-offset-3 col-md-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"><i class="fa fa-home"></i><span>SECTION-1</span></a></li>
                    <li role="presentation"><a href="#Section2" aria-controls="profile" role="tab" data-toggle="tab"><i class="fa fa-globe"></i><span>SECTION-2</span></a></li>
                    <li role="presentation"><a href="#Section3" aria-controls="messages" role="tab" data-toggle="tab"><i class="fa fa-briefcase"></i><span>SECTION-3</span></a></li>
                </ul>
                <!-- Tab panes -->
                <div class="tab-content tabs">
                    <div role="tabpanel" class="tab-pane fade in active" id="Section1">
                        <h3>Section 1</h3>
                        <p>选项卡一的内容</p>
                    </div>
                    <div role="tabpanel" class="tab-pane fade" id="Section2">
                        <h3>Section 2</h3>
                        <p>选项卡二的内容</p>
                    </div>
                    <div role="tabpanel" class="tab-pane fade" id="Section3">
                        <h3>Section 3</h3>
                        <p>选项卡三的内容</p>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
