将使用 :before & :after 创建的 div 与其他元素水平对齐

Question

我正在使用 :before 创建一个黑色圆圈（它应该显示白色文本恰好居中，无法弄清楚为什么它不是白色）和 :after 显示虚线线（如图所示）。我希望黑色圆圈（里面有文字）与输入水平放置，但我一直遇到问题，因为它也在它和后面的虚线之间产生了很大的差距。我玩过边距，但我不想将元素推得太远。

.progress-container {
  display: flex;
  position: relative;
}

.progress-indicator {
  position: relative;
  display: inline-block;
  margin-bottom: 40px;
  color: #fff;
}

.progress-indicator::before {
    content: "";
    width: 22px;
    height: 22px;
    background: #000;
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    border-radius: 50%;
}

.progress-indicator::after {
    content: "";
    height: 85px;
    border: 2px dashed #a9b4b8;
    position: absolute;
    left: 50%;
    top: 49px;
    transform: translateX(-50%);
    margin-bottom: 10px;
}

.input-container {
  display: flex;
  align-items: center;
}

.input-wrapper {
  border: 1px solid #ced4da;
  border-radius: 2px;
  overflow-y: hidden;
  padding: 0.375rem 1.75rem 0.375rem 0.75rem;
  margin-left: 30px;
}

<div class=progress-container>
  <div class="progress-indicator">1</div>
  <div class="input-container">
    <div class="input-wrapper">
      <div>Input</div>
    </div>
  </div>
</div>

注意：您的 .progess-container 选择器中有错字正确：.progress-container

编辑了您的 CSS：

.progress-container {
  display: flex;
  flex-direction: row;
  align-items: center;
  position: relative;
}

.progress-indicator {
  position: relative;
  display: inline-block;
  color: #fff;
}

.progress-indicator::before {
    content: "";
    width: 22px;
    height: 22px;
    background: #000;
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    border-radius: 50%;
  z-index: -1;
}

.progress-indicator::after {
    content: "";
    height: 85px;
    border: 2px dashed #a9b4b8;
    position: absolute;
    left: 50%;
    transform: translateX(-50%);
    margin-bottom: 10px;
  z-index: -2;
}

.input-container {
  display: flex;
  align-items: center;
}

.input-wrapper {
  border: 1px solid #ced4da;
  border-radius: 2px;
  overflow-y: hidden;
  padding: 0.375rem 1.75rem 0.375rem 0.75rem;
  margin-left: 30px;
}

<div class=progress-container>
  <div class="progress-indicator">1</div>
  <div class="input-container">
    <div class="input-wrapper">
      <div>Input</div>
    </div>
  </div>
</div>
