这是一款非常简单的Bootstrap Tabs选项卡美化特效。该特效在原生Bootstrap Tabs选项卡的基础上，通过css3来对它进行了一些美化效果。

使用方法

在页面中引入jquery和bootstrap相关文件。

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

该Bootstrap Tabs选项卡使用下面的HTML结构：

<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">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>
                </ul>
                <!-- Tab panes -->
                <div class="tab-content tabs">
                    <div role="tabpanel" class="tab-pane fade in active" id="Section1">
                        <h3>选项卡 1</h3>
                        <p>....</p>
                    </div>
                    <div role="tabpanel" class="tab-pane fade" id="Section2">
                        <h3>选项卡 2</h3>
                        <p>...</p>
                    </div>
                    <div role="tabpanel" class="tab-pane fade" id="Section3">
                        <h3>选项卡 3</h3>
                        <p>....</p>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
