CSS和HTML的水平家谱

Question

我在网上搜索过，发现后来在codepen中编辑了一个很好的家谱例子：http://codepen.io/anon/pen/bdLeNe。我的代码如下。

我正在努力解决2（css）问题：

• 1：我需要调整树，以便在每个父链接的末尾（它与子级别相交）我可以画一个圆圈，但我唯一得到的就是在链接下面画圆圈。

这样的事情：

      ----- LN
      |
P --- O
      |
      ----- LN

其中P是Parent和LN叶节点。

• 2：在原始示例中，叶节点没有内容（p，输入等）。如果他们在任何这些元素<span class="label">中都有它，它们会与它的兄弟重叠。我不知道如何使它们在相对定位时具有可变高度。我试过margin-top，但问题是链接不够高（节点断开连接）

我创建了一个要点：https://gist.github.com/leolanchas/9887b4e68db9f5894c9c
