我有一个简单的表单样式,开发用于显示树。每张纸都可以有很多或任何一个孩子。
几个节点样式表运行良好,但是大量行为不正确。
具有许多节点的树的示例(出现故障,您可以看到树被切割和跳下的方式):
如果我将div宽度强制为特定宽度,我得到我想要的结果,但我需要自动机制,如果可能的话保持纯CSS。示例树运行良好,手动设置宽度:
更具体地说,无论屏幕的大小如何,我都会自动寻找树的宽度,并且必须使用滚动来完全看到它。标签的内容长度可能不同,因此其大小可自行调整。
这是我的样式表和示例树:
* {margin: 0; padding: 0;}
/*.tree{width:3000px; margin:40px auto 0 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;

我感谢您花时间帮助我。提前谢谢。

99%的解决方案:
给DIV一个实际宽度 - 100%的父级。
div.tree {
margin:40px auto 0 auto;
width:100%;
overflow-x:auto;
}
似乎是包装其内容的UL。 使用nowrap来阻止空格包装。
.tree ul {
white-space:nowrap;
padding-top: 20px; position: relative;
transition: all 0.5s;
-webkit-transition: all 0.5s;
-moz-transition: all 0.5s;
}
最后将LI转换为块显示,停止向左浮动,并修复丢失的左浮动,将它们与容器顶部对齐。
.tree li {
display:inline-block;
vertical-align:top;
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;
}
缺少1%是水平线之间的几个像素间隙。不知道如何关闭它。保证金和垫子也许?我似乎无法管理它。

更改
/*.tree{width:3000px; margin:40px auto 0 auto}*/
到
.tree{
width: 2000px;
margin: 40px auto 0 auto;
overflow-x: scroll;
overflow-y: hidden;
}
随着树中节点的增长,调整width
。
* {margin: 0; padding: 0;}
.tree{width: 2000px; margin:40px auto 0 auto;overflow-x: scroll;
overflow-y: hidden;}
.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;
