基本的进度条组成是

***小demo***

<!DOCTYPE html>
    <html>
    <head>
    	<meta charset="utf-8"> 
    	<title> 进度条</title>
    	<script type="text/javascript" src="js/jquery.min.js" ></script>
    	
    	<link rel="stylesheet" href="css/bootstrap.min.css" />
    	<script type="text/javascript" src="js/bootstrap.min.js" ></script>
    </head>
    <body>
    	bootstrap
    	<div class="progress">
    		<div class="progress-bar" style="width: 40%;">
    		</div>
    	</div>
    </body>
    </html>

***进度条堆叠***

<div class="progress">
    		<div class="progress-bar progress-bar-info" style="width: 30%;">
    			<span>30% 完成（信息）</span>
    		</div>
    		<div class="progress-bar progress-bar-warning" style="width: 20%;">
    			<span>20% 完成（警告）</span>
    		</div>
    		<div class="progress-bar progress-bar-danger"style="width: 10%;">
    			<span>10% 完成（危险）</span>
    		</div>
    		<div class="progress-bar progress-bar-self"style="width: 30%;">
    			<span>30% 自定义</span>
    		</div>
    		<div class="progress-bar progress-bar-self"style="width: 35%;">
    			<span>35% 斜纹</span>
    		</div>
    	</div>
