Question

我从CSS3族树的实验性多父版本开始：http://thecodeplayer.com/experiment/css3-family-tree/2

但是我与多个父母（家谱中的合作伙伴）有一些对齐问题，这似乎是由框中文本的长度引起的。如果两个盒子的长度相同，则它们排成一行，否则较长的一个较高，高度的差异与长度的差异成正比。

此外，那里的任何一个孩子似乎都向左浮动，而不是像他们应该那样集中坐着。 编辑：此部分已经回答

任何想法可能导致这个/我如何解决它？

Answer 1

添加缺少的垂直对齐方式。

http://jsfiddle.net/7g7fz2tL/6/

.tree li a {
  height: 60px;
  width: 60px;
  vertical-align: top; /*THIS*/
}

Answer 2

向曾孙子们添加一个类，并将float设置为none，如下所示：

ul li.great-grandchild {
    float:none;
}
