见图--在此树中，“独生子女”与其他儿童不水平对齐：

​

​

我可以看到这是由CCS造成的，因为CCS从单个子节点的顶部删除了空间，但是删除CSS显示垂直行太短：

​

​

有谁能解决如何使独生子女与其他孩子水平一致的问题？

谢谢

尝试下面的代码片段，以下是更改

only-child

  • removed padding

  • removed
  • 为第一个列表元素

添加了伪类。

代码语言：javascript
复制
*.genealogy-tree li:last-child:only-child::after, .genealogy-tree li:last-child:only-child::before {
  content: '';
  position: absolute; 
  top: 0; 
  left: 50%;
  width: 0;
  height: 18px;
  border-radius: 0;
}

.genealogy-tree > ul > li::after, .genealogy-tree > ul > li::before {
  display: none
}

.genealogy-tree li:only-child{ 
/* padding-top: 0; */
}
