如何在ul / li CSS树中区分“没有孙子女但有很多孩子的父母”(例如http://reporting.MYSITE.com/cgi-bin/rr/blank.gif?nourl=category-viewed&view_event=yes&view_category=category&view_name=Sale)?
最终目标是使树适合8.5“x 11”并且能够处理具有很长文本的li。如果可以的话,我想坚持使用纯CSS(我不是100%确定生产环境允许jQuery / JS /等。)
这是我上面示例中的CSS代码,略有修改:
* {
margin: 0;
padding: 0;
}
.tree {
white-space: nowrap;
}
.tree ul {
padding-top: 20px;
position: relative;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
.tree li {
float: none;
display:inline-block;
white-space: wrap;
vertical-align:top;
margin: 0 -2px 0 -2px;
text-align: center;
list-style-type: none;
position: relative;
padding: 20px 5px 0 5px;
width: auto;
margin-bottom: 10px;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
.tree li span {
}
.tree li span.rotated {
-ms-writing-mode: tb-rl; /* old syntax. IE */
-webkit-writing-mode: vertical-rl;
-moz-writing-mode: vertical-rl;
-ms-writing-mode: vertical-rl;
writing-mode: vertical-rl; /* new syntax */
}
.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;
}
.tree li:only-child::after, .tree li:only-child::before {
display: none;
}
.tree li:only-child {
padding-top: 0px;
float: none;
}
.tree li:first-child::before, .tree li:last-child::after {
border: 0 none;
}
.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;
}
.tree ul ul::before {
content: '';
position: absolute;
top: 0;
left: 50%;
border-left: 1px solid #ccc;
width: 0;
height: 20px;
}
.tree li span {
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;
}

目前CSS中没有parent
