源代码是这个
.progress-bar {
float: left;
width: 0;
height: 100%;
font-size: 12px;
line-height: 20px;
color: #fff;
text-align: center;
background-color: #337ab7;
-webkit-box-shadow: inset 0 -1px 0 rgba(0, 0, 0, .15);
box-shadow: inset 0 -1px 0 rgba(0, 0, 0, .15);
-webkit-transition: width .6s ease;
-o-transition: width .6s ease;
transition: width .6s ease;
}
好像只能修改float和background-color,没有其他的方法了吗
