剪辑路径，如何创建循环进度条？

Question

我已经看到很多创建圆形进度条的解决方案。它们似乎都非常漫长而且令人费解。我想创建一个非常简单的一个，只需在彼此的顶部绘制两个圆圈并剪切一个外部的一部分，以便创建一个小于100％的进度条外观。

我的HTML

    <div class="outter">
      <div class="inner"></div>
    </div>

我的CSS

.outter {
  background-color: #08a1db;
  width: 100px;
  height: 100px;
  border-radius: 50%;
  position: relative;
}

.inner {
  background-color: white;
  width: 84px;
  height: 84px;
  border-radius: 50%;
  position: absolute;
  top: 50%;
  left: 50%;
  margin: -42px 0 0 -42px;
}

现在我遇到麻烦的部分是使用剪辑路径。我无法从文档中弄清楚如何剪辑出局圈并创建进度条的效果。有什么建议吗？

剪辑css运算符标记为已弃用并被 clip-path 替换，而 IE 则不完全支持 。< / p>

使用剪辑

.progress-circle {
  font-size: 20px;
  margin: 20px;
  position: relative;
  /* so that children can be absolutely positioned */
  padding: 0;
  width: 5em;
  height: 5em;
  background-color: #F2E9E1;
  border-radius: 50%;
  line-height: 5em;
}

.progress-circle:after {
  border: none;
  position: absolute;
  top: 0.35em;
  left: 0.35em;
  text-align: center;
  display: block;
  border-radius: 50%;
  width: 4.3em;
  height: 4.3em;
  background-color: white;
  content: " ";
}


/* Text inside the control */

.progress-circle span {
  position: absolute;
  line-height: 5em;
  width: 5em;
  text-align: center;
  display: block;
  color: #08a1db;
  z-index: 2;
}

.left-half-clipper {
  /* a round circle */
  border-radius: 50%;
  width: 5em;
  height: 5em;
  position: absolute;
  /* needed for clipping */
  clip: rect(0, 5em, 5em, 2.5em);
  /* clips the whole left half*/
}


/* when p>50, don't clip left half*/

.progress-circle.over50 .left-half-clipper {
  clip: rect(auto, auto, auto, auto);
}

.value-bar {
  /*This is an overlayed square, that is made round with the border radius,
   then it is cut to display only the left half, then rotated clockwise
   to escape the outer clipping path.*/
  position: absolute;
  /*needed for clipping*/
  clip: rect(0, 2.5em, 5em, 0);
  width: 5em;
  height: 5em;
  border-radius: 50%;
  border: 0.45em solid #08a1db;
  /*The border is 0.35 but making it larger removes visual artifacts */
  /*background-color: #4D642D;*/
  /* for debug */
  box-sizing: border-box;
}


/* Progress bar filling the whole right half for values above 50% */

.progress-circle.over50 .first50-bar {
  /*Progress bar for the first 50%, filling the whole right half*/
  position: absolute;
  /*needed for clipping*/
  clip: rect(0, 5em, 5em, 2.5em);
  background-color: #08a1db;
  border-radius: 50%;
  width: 5em;
