我从 CSS3 Family Tree 的实验性多父版本开始：http://thecodeplayer.com/experiment/css3-family-tree/2 http://thecodeplayer.com/experiment/css3-family-tree/2
不过我有一些对齐问题有多个父母（家谱中的合作伙伴），这似乎是由框中文本的长度引起的。如果两个盒子的文本长度相同，它们就会排成一行，否则越长的盒子越高，并且高度差与长度差成正比。
而且，任何一个孩子自己似乎都会飘到左边，而不是像他们应该的那样坐在中间。编辑：这部分已得到答复
示例如下：http://jsfiddle.net/7g7fz2tL/5/ http://jsfiddle.net/7g7fz2tL/5/

有什么想法可能导致此问题/我该如何解决它？
添加缺少的垂直对齐方式。
