html - Stepper 纯 HTML CSS

Question

我对自己创建的进度条感到困惑。

我希望进度条在将类设置为“事件”后将其背景颜色更改为蓝色。但是我希望进度条在类设置为“事件”之前更改其背景颜色。

这是我的 HTML:

<ul class="progressBar">
  <li class="active">Beong Processed</li>
  <li class="active">Waiting for payment</li>
  <li>Paid</li>
</ul>

……和 CSS:

.progressBar li.active {
  color: dodgerblue;
}
.progressBar li.active:before {
  border-color: dodgerblue;
  background-color: dodgerblue
}
.progressBar li.active + li:after {
  background-color: dodgerblue;
}

结果是这样的

我希望它是这样的

使用 .progressBar .active:after 而不是 .progressBar li.active + li:after

+ 在 css 中

It is Adjacent sibling combinator. It combines two sequences of simple selectors having the same parent and the second one must come IMMEDIATELY after the first.

.wrapper-progressBar {
    width: 100%
}

.progressBar {
}

.progressBar li {
    list-style-type: none;
    float: left;
    width: 33%;
    position: relative;
    text-align: center;
}

.progressBar li:before {
    content: " ";
    line-height: 30px;
    border-radius: 50%;
    width: 30px;
    height: 30px;
    border: 1px solid #ddd;
    display: block;
    text-align: center;
    margin: 0 auto 10px;
    background-color: white
}

.progressBar li:after {
    content: "";
    position: absolute;
    width: 100%;
    height: 4px;
    background-color: #ddd;
    top: 15px;
    left: -50%;
    z-index: -1;
}

.progressBar li:first-child:after {
    content: none;
}

.progressBar li.active {
    color: dodgerblue;
}

.progressBar li.active:before {
    border-color: dodgerblue;
    background-color: dodgerblue
}

.progressBar .active:after {
    background-color: dodgerblue;
}

<div class="row">
  <div class="col-xs-12 col-md-8 offset-md-2 block border">
    <div class="wrapper-progressBar">
      <ul class="progressBar">
        <li class="active">Beong Processed</li>
        <li class="active">Waiting for payment</li>
        <li>Paid</li>
      </ul>
    </div>
  </div>
</div>
