html - tds 中圆圈之间的车道

Question

我如何在这些圆圈之间放置车道，我一直在谷歌搜索，但我没有看到最简单的方法，

.table_1 {
  tr {
    color: #000000;
    font-size: 20px;
    letter-spacing: 0.4px;
    line-height: 30px;
    td:nth-child(2) {
      vertical-align: baseline;
    }
    td:nth-child(1) {
      display: flex;
      justify-content: center;
      margin-right: 28px;
      width: 42px;
      height: 42px;
      display: block;
      border: 1px solid #999999;
      border-radius: 100%;
      text-align: center;
      margin-bottom: 31%;
      span {
        vertical-align: middle;
        color: #999999;
        font-size: 24px;
        line-height: 32px;
        text-align: center;
      }
    }
  }
}

编辑...我想用类似的线连接所有的圈子

Answer 1

是这样的吗？ css有注释

tr {
  color: #000000;
  font-size: 20px;
  letter-spacing: 0.4px;
  line-height: 30px;
}

td {
  display: flex;
  justify-content: center;
  margin-right: 28px;
  width: 42px;
  height: 42px;
  display: block;
  border: 1px solid #999999;
  border-radius: 100%;
  text-align: center;
  margin-bottom: 31%;

  /* making the element relative to position the lane relative to it */
  position: relative;
}


/* Selecting all td except the last one and using pseudo-class :after to shape the lane */

tr:not(:last-child)>td:before {
  content: '';
  position: absolute;
  background: red;
  height: 20px;
  width: 4px;
  top: 110%;
  left: 50%;
  transform: translateX(-50%)
}

span {
  vertical-align: middle;
  color: #999999;
  font-size: 24px;
  line-height: 32px;
  text-align: center;
}

<table class="table_1">
  <tbody>
    <tr>
      <td><span>1</span></td>
    </tr>
    <tr>
      <td><span>2</span></td>
    </tr>
    <tr>
      <td><span>3</span></td>
    </tr>
    <tr>
      <td><span>4</span></td>
    </tr>
    <tr>
      <td><span>5</span></td>
    </tr>
  </tbody>
</table>
