请查看plnkr。我试图填补垂直线之间的差距。有人能帮我吗。我对比实现这种造型更好的方式持开放态度

这里有你需要的东西。

.parent .parent-header:after {
  top: 35px;
}

.child-header {
  margin-top:0;
  padding-top:25px;
}

.child:last-child .child-header:before {
  height: 35px;
}

基本上造成这种差距的是来自h2.child-header的边距。因此，您需要更改它以进行填充，然后只需修改.child-header：在最高值之后即可。

希望我能够帮助你。

在你的风格中添加元素默认填充和边距0。

*{
    margin: 0;
    padding : 0;
  }

当您检查代码时，可以看到元素示例h2的默认样式

 h2 {
display: block;
font-size: 1.5em;
-webkit-margin-before: 0.83em;
-webkit-margin-after: 0.83em;
-webkit-margin-start: 0px;
-webkit-margin-end: 0px;
font-weight: bold;

}
