如何在进度点的边界上叠加进度条线？

Question

因此，我正在开发一个带有步骤的进度向导，但我很难尝试通过进度条运行获得圆形进度步骤的特定外观。这是我在 Copepen 上的 HTML/CSS：

最终，目标是让灰色 and/or 绿色进度线直接合并到实心圆进度步骤（深灰色或绿色）中。此时，灰色或绿色的进度线停在进度圈上设置的边框处：

最终目标是让它看起来像这个 PSD 示例：

.container {
  width: 960px;
  margin: 50px auto;
  font-family: Arial, sans-serif;
}

.progress-wrap {
  height: 16px;
  background: #e4e4e4;
  border-radius: 3px;
  border-top: 1px solid #ccc;
}

.progress-wizard {
  padding: 0 0 10px 0;
  position: relative;
  bottom: 10px;
  list-style-type: none;
}

.progress-wizard li {
  display: inline-block;
  width: 16%;
  height: 36px;
  font-size: 12px;
  text-align: center;
  text-indent: -19px;
  line-height: 75px;
  border-top: 4px solid #ccc;
  box-shadow: inset 0 1px 0 #fff;
  position: relative; 
  z-index: 1 !important;
}

.progress-wizard li:before {
  position: relative;
  float: left;
  text-indent: 0;
  left: -webkit-calc(50% - 9.5px);
  left: -moz-calc(50% - 9.5px);
  left: -ms-calc(50% - 9.5px);
  left: -o-calc(50% - 9.5px);
  left: calc(50% - 9.5px);
}

.progress-wizard li.done {
  font-size: 12px;
}

.progress-wizard li.done:before {
  content: "✔" !important;
  color: white !important;
  text-shadow: none !important;
  font-size: 14px;
  height: 30px;
  width: 30px;
  line-height: 30px;
  top: -19px;
  border: none;
  border-radius: 19px;
  box-shadow: 0 -1px 0 0 #ccc;
}

.progress-wizard li.todo {
  font-size: 12px;
  border-top-color: #ccc;
  position: relative;
  color: #999;
}

.progress-wizard li.todo:before {
  content: "B24";
  font-size: 17.1px;
  top: -22px;
  line-height: 18.05px;
}

.progress-wizard li.done {
  color: #8c9c58;
  border-top-color: #8c9c58;
}

.progress-wizard li.done:before {
  color: white;
  background-color: #8c9c58;
  border: 5px solid #e4e4e4;
  position: relative;
  top: -22px;
}

.progress-wizard li.todo:before {
  background: #ccc;
  width: 30px;
  height: 30px;
  border: 5px solid #e4e4e4;
  box-shadow: 0 -1px 0 0 #ccc;
  border-radius: 60px;
  line-height: 30px;
}

.progress-wizard li.stepone:before {
  color: #999;
  text-shadow: 1px 1px 0 white;
  content: "1";
}

.progress-wizard li.steptwo:before {
  color: #999;
  text-shadow: 1px 1px 0 white;
  content: "2";
}

.progress-wizard li.stepthree:before {
  color: #999;
  text-shadow: 1px 1px 0 white;
  content: "3";
}

.progress-wizard li.stepfour:before {
  color: #999;
  text-shadow: 1px 1px 0 white;
  content: "4";
}

.progress-wizard li.stepfive:before {
  color: #999;
  text-shadow: 1px 1px 0 white;
  content: "5";
}

.progress-wizard li.stepsix:before {
  color: #999;
  text-shadow: 1px 1px 0 white;
  content: "6";
}

.progress-wizard li.current {
  color: #93b5d3;
}

.progress-wizard li.current:before {
  background: #93b5d3;
  color: #fff;
  text-shadow: none;
}

<div class="container">
 <div class="progress-wrap">
  <ol class="progress-wizard">
    <li class="progress-point done stepone">Information</li><li class="progress-point current todo steptwo">Related Items</li><li class="progress-point todo stepthree">Access</li><li class="progress-point todo stepfour">Uploads</li><li class="progress-point todo stepfive">Availability</li><li class="progress-point todo stepsix">Review</li>
  </ol>
  </div>
</div>

我在想，为了解决这个问题，它可能与伪元素的 z-index 和伪元素的父元素有关，但我已经尝试了几件事，但没有成功。任何投入将不胜感激。

谢谢！

Answer 1

难道是这个？

.progress-wizard li.done:after {
  content: " ";
  background-color: #ccc;
  position: absolute;
  top: -4px;
  padding-right: 47px;
  left: 107px;
  height: 4px;

}

编辑：

刚看到一个小问题。您必须仅将此 :after 元素添加到最后一个完成的元素。否则它会覆盖进度条。还好吗？可以用JS去除。

Answer 2

在Bootstrap

.progress-wizard li:before {
  position: relative;
  float: left;
  text-indent: 0;
  left: -webkit-calc(50% - 9.5px);
  left: -moz-calc(50% - 9.5px);
  left: -ms-calc(50% - 9.5px);
  left: -o-calc(50% - 9.5px);
  left: calc(50% - 9.5px);
  box-sizing: content-box;
}
