html - CSS组织结构图

Question

我有一个 HTML & CSS 组织结构图，我认为这是一个简单的问题。 这是 JSFiddle 中的演示

CSS

    /*Now the CSS*/
* {margin: 0; padding: 0;}

.tree

{
width: auto;

margin-left: auto;
margin-right: auto;
}

.tree ul {
padding-top: 20px; position: relative;

transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}

.tree li {
float: left; text-align: center;
list-style-type: none;
position: relative;
padding: 20px 5px 0 5px;

transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}

/*We will use ::before and ::after to draw the connectors*/

.tree li::before, .tree li::after{
content: '';
position: absolute; top: 0; right: 50%;
border-top: 1px solid #ccc;
width: 50%; height: 20px;
}

.tree li::after{
right: auto; left: 50%;
border-left: 1px solid #ccc;
}

/*We need to remove left-right connectors from elements without 
any siblings*/

.tree li:only-child::after, .tree li:only-child::before {
display: none;
}

/*Remove space from the top of single children*/
.tree li:only-child{ padding-top: 0;}

/*Remove left connector from first child and 
right connector from last child*/
.tree li:first-child::before, .tree li:last-child::after{
border: 0 none;
}

/*Adding back the vertical connector to the last nodes*/
.tree li:last-child::before{
border-right: 1px solid #ccc;
border-radius: 0 5px 0 0;
-webkit-border-radius: 0 5px 0 0;
-moz-border-radius: 0 5px 0 0;
}

.tree li:first-child::after{
border-radius: 5px 0 0 0;
-webkit-border-radius: 5px 0 0 0;
-moz-border-radius: 5px 0 0 0;
}

/*Time to add downward connectors from parents*/

.tree ul ul::before{
content: '';
position: absolute; top: 0; left: 50%;
border-left: 1px solid #ccc;
width: 0; height: 20px;
}


.tree li a{
border: 1px solid #ccc;
padding: 5px 10px;
text-decoration: none;
color: #666;
font-family: arial, verdana, tahoma;
font-size: 11px;
display: inline-block;

border-radius: 5px;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;

transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}

/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}

/*Connector styles on hover*/

.tree li a:hover+ul li::after, 
.tree li a:hover+ul li::before,
.tree li a:hover+ul::before,
.tree li a:hover+ul ul::before{
border-color:  #94a0b4;
}

我想做的是:如何在 IT 支持之前排队 - David Alwis。因为我们看到职位与 IT 相同 - 支持 Juanda。

请大家帮忙!

jsFiddle Demo

添加了这些样式:

.tree ul ul::before{
    margin-left: -1px;
}
li a.just-line {
    display: none;
}
a.just-line + ul {
    padding-top: 74px;
}
a.just-line + ul:before {
    height: 74px;
}
