需求背景
在vue项目开发中,涉及到流量的使用情况,采用el-progress进度条来显示目前流量的状态。由于流量是越来越少,所以要采用逆向的方式来显示出来。el-progress示例中都是正向的方式,我们这里是做了一小部分修改,达到了想要的效果,如图。

>>>.el-progress-bar{ margin-bottom:20px;}
</style>
核心代码
解决问题的办法,就是修改el-progress的样式,left: auto;right: 0; 这是核心
>>>.el-progress-bar__inner{text-align: right;left: auto;right: 0; border: 1px solid #fff;}
