Family tree(族谱),也称家谱,用来记录家族世系繁衍辈份关系。本文结合实例,不借助任何js脚本,使用纯CSS打造一个漂亮的Family tree(族谱),也可以应用的企业组织架构图中。

利用CSS实现Family tree(族谱)效果

HTML
我们使用div#tree来包含整个族谱结构,内部以ul和li元素构建数据源。实际开发中这些族谱数据源可以从数据库中读取,就像得到一个无限级的分类列表,以下是主要的html结构。
 

   
       
            Parent
           
               
                    Child
                   
                        Grand Child
                   
               
               
                    Child
                   
                        Grand Child
                       
                            Grand Child
                           
                                Great Grand Child
                                Great Grand Child
                                Great Grand Child
                           
                       
                        Grand Child
                   
               
           
       
   

CSS

我们使用css中的 :before、:after 两个伪类的content属性来构建元素间的连接线,同时使用了css3实现元素的圆角效果,并加上了鼠标滑上hover效果,这样鼠标滑向族谱中的一个节点元素,与之相关的后辈元素都会有hover效果,完整的css代码如下:
 
.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;
}
