【Bootstrap 进度条】
1、基础进度条
<div class="progress"> <div class="progress-bar" style="width: 40%;"> </div> </div>
1）根div必须 class="progress"
2）前景div为 class="progress-bar", 通过style指定宽度
2、指定颜色.
progress-bar-success、progress-bar-info、progress-bar-warning、progress-bar-danger
<div class="progress"> <div class="progress-bar progress-bar-success"style="width: 90%;"> </div> </div> <div class="progress"> <div class="progress-bar progress-bar-info" style="width: 30%;"> </div> </div> <div class="progress"> <div class="progress-bar progress-bar-warning" style="width: 20%;"> </div> </div> <div class="progress"> <div class="progress-bar progress-bar-danger" style="width: 10%;"> </div> </div>
3、条纹状，通过在根div添加 progress-striped 即可
<div class="progress progress-striped"> <div class="progress-bar progress-bar-success" style="width: 90%;"> </div> </div>
4、在根div 添加active，即可实现带动画的进度条。
<div class="progress progress-striped active"> <div class="progress-bar progress-bar-success" style="width: 40%;"> </div> </div>
