中心二进制树与css或js

我需要用css或js集中这个二叉树。

Jquery是一个可用选项。

html代码将由php脚本嵌套数组格式生成。

我已创建此Fiddle以寻求帮助。

提前致谢

HTML:

此解决方案可能对您有所帮助。它使用css3(没有javascript)来绘制一个简单的二叉树。这是jsfiddle demostep by step tutorial

<强> HTML:

<!--
We will create a family tree using just CSS(3)
The markup will be simple nested lists
-->
<div class="tree">
    <ul>
        <li>
