我正在尝试使用HTML和CSS构建家谱。我在codepen上找到了一个很好的例子。
由于家庭关系不仅仅是简单的节点层次结构，有时候还涉及到复杂的关系，我需要拥有多个几乎可以作为一个节点的节点。但现在我们从最简单的例子开始，以我的母亲一方的祖母为根节点，以我的家族为例：
- 我有一个父亲，他是我母亲的前夫
- 我的母亲再婚了，因此我有个继父
所以上面的基础节点是我的母亲，但是我和我的姐姐应该放在我的父亲下面，因为我们与继父没有关系。我试图在这里画出来：
以下是我的标记和CSS（基于上面的codepen示例）：
/* Person */

</div>编辑：我找到了一个解决方案，即在后端计算显示在一起的节点，然后写一些带宽度的样式属性到一个新引入的div中。它还不完美，如果有改进的地方，请发表评论或回答。
以下是构建方法：
.persondivs以及.parent与子元素，使得线条从该节点出发... 因此，欢迎任何可以使其工作的标记和CSS更改。 - Thomas
