这是一款CSS3彩色进度条动画特效。该进度条通过对bootstrap原生进度条的改造，制作出效果非常炫酷的进度条动画效果。

 使用方法

在页面中引入jquery和bootstrap相关文件。

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

 HTML结构

该CSS3进度条的HTML结构如下：

<div class="container">
    <div class="row">
        <div class="col-md-offset-3 col-md-6">
            <h3 class="progress-title">HTML5</h3>
            <div class="progress">
                <div class="progress-bar" style="width:65%; background:#ef2d56;">
                    <div class="progress-value">65%</div>
                </div>
            </div>
 
            <h3 class="progress-title">CSS3</h3>
            <div class="progress">
                <div class="progress-bar" style="width:87%; background:#ff9900;">
                    <div class="progress-value">87%</div>
                </div>
            </div>
 
            <h3 class="progress-title">J-Query</h3>
            <div class="progress">
                <div class="progress-bar" style="width:55%; background:#82b700;">
                    <div class="progress-value">55%</div>
                </div>
