这种阶段性的进度条怎么做。

Question

请问这种类似的效果图怎么做，或者有没有类似的demo链接发一下

Answer 1

有两套图片（绿色的圆形图和灰色的圆形图，是不是灰色的我不清楚，反正就是默认的那种图），有两个颜色的进度线条，（灰色和绿色的），然后和楼上的思路是一样的，就是图片的两种class名称的切换，和两种class名称的线条的长度改变，比如（我只写线条的，懒得去找图片，反正方式是一样一样的）：.line{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; position: relative;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .default{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; position: absolute;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; margin: 0;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; padding: 0;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; width: 100%;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-bottom: 2px solid #999;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-top: none;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-left: none;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-right: none;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; .runing{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; position: absolute;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; margin: 0;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; padding: 0;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; width: 80%;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-bottom: 2px solid #e4393c;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-top: none;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-left: none;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; border-right: none;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="line">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <hr class="default"/>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <hr class="runing"/>&nbsp; &nbsp; &nbsp; &nbsp; </div>你要做的就是用js配合，动态修改runing的宽度就Ok了，那个图片其实也差不多的，根据runing的长度，来切换图片（你甚至可以把一切都写死，前提是该效果有多个页面，并且都是静态的页面）
