具有透明度的CSS Stepped Progress Bar

问题描述 投票：1回答：1

任何人都可以帮我在仅使用CSS的步进式进度条中围绕圆圈放置透明边框吗？

有很多好的开始，比如这篇文章：Creating CSS3 Circles connected by lines

这个网站：https://www.cssscript.com/animated-step-progress-bar-pure-javascript/

或者这个网站：http://christabor.github.io/css-progress-wizard/

我的问题是我需要一条线穿过圆圈的透明边框。在此示例中，绿线越过圆圈的灰色边框的顶部。

根据上面的一个示例，您可以从这里开始使用笔。 https://codepen.io/anon/pen/oPydjx

因为线条绝对是位置元素，所以它们出现在气泡上方。您可以在气泡中添加box-shadow以获得效果：

.progress-indicator>li .bubble {
  box-shadow: 0 0 0 3px rgba(0, 0, 0, 0.1);

  border-radius: 50%;
  width: 20px;
  height: 20px;
  background-color: #bbb;
  display: block;
  margin: 0 auto .5em;
  border-bottom: 1px solid #888;
}

例：

body {
  font-family: 'Lato', sans-serif;
  font-size: 20px;
  padding: 20px;
}

@media handheld,
screen and (max-width: 400px) {
  .container {
    margin: 0;
    width: 100%;
  }
  .progress-indicator.stacked {
    display: block;
    width: 100%;
  }
  .progress-indicator.stacked>li {
    height: 80px;
  }
}

.flexer,
.progress-indicator {
  display: flex
}

.flexer-element,
.progress-indicator>li {
  flex: 1
}

.progress-indicator>li {
  list-style: none;
  text-align: center;
  width: auto;
  padding: 0;
  margin: 0;
  position: relative;
  text-overflow: ellipsis;
  color: #bbb;
  display: block
}

.progress-indicator>li.completed,
.progress-indicator>li.completed .bubble {
  color: #65d074
}

.progress-indicator>li .bubble {
  box-shadow: 0 0 0 3px rgba(0, 0, 0, 0.1);
  
  border-radius: 50%;
  width: 20px;
  height: 20px;
  background-color: #bbb;
  display: block;
  margin: 0 auto .5em;
  border-bottom: 1px solid #888;
}

.progress-indicator>li .bubble:after,
.progress-indicator>li .bubble:before {
  display: block;

  top: 9px;
  width: 100%;
  height: 3px;
  content: '';
  background-color: #bbb
}

.progress-indicator>li.completed .bubble,
.progress-indicator>li.completed .bubble:after,
.progress-indicator>li.completed .bubble:before {
  background-color: #65d074;
  border-color: #247830
}

.progress-indicator>li .bubble:before {
  left: 0
}

.progress-indicator>li .bubble:after {
  right: 0
}

.progress-indicator>li:first-child .bubble:after,
.progress-indicator>li:first-child .bubble:before {
  width: 50%;
  margin-left: 50%
}

.progress-indicator>li:last-child .bubble:after,
