纯CSS 实现组织架构图，学习

先上张图

Css 代码如下：

div#contain {
 1000em;
 background:#fff;
 font-family:verdan;
}
 ul#xflow {
 float: none;
 margin: 0 auto;
}
 ul {
 clear: left;
 margin: 2em 0 0 0;
 padding: 0;
 background: #fff;
}
 ul ul {
 border-top: 1px solid #000;
  auto;
}
 ul.solo {
 border-top: 0;
}
 li {
 float: left;
 list-style: none;
 position: relative;
}
 li li {
 margin: -1px 0 0 0;
}
#xflow div{
 background: url(../img/Flow/vLine.gif) 50% repeat-y;
 padding: 2em 5px 0 5px;
 margin: 0 .3em -2em 0em;
}
#xflow div.section {
 padding: 2em 5px 2em 5px;
}
#xflow div.first {
 background: url(../img/Flow/first.gif) 50% repeat-y;
 margin-left: 0;
}
#xflow div.last {
 background: url(../img/Flow/last.gif) 50% repeat-y;
 margin-right:0;
}
.none{border:0px;}
#xflow div.root {
 padding-top: 0;
}
#xflow a {
 display: block;
 background: #fff;
 border: 1px solid #000;
 padding: .25em .2em .2em .2em;
 color: #222;
 text-decoration: none;
 margin: 0 auto;
  10em;
 line-height: 2em;
 text-align: center;
}

/*IE 6 (when comma-separated, IE6 didn't work, so these are duped for IE7)*/
*html  {text-align: center;}
*html  a {margin: 0; position: relative;}
/*IE 7*/
*:first-child+html  {text-align: center;}
*:first-child+html  a {margin: 0; position: relative;}
