好吧，我使用它作为what i want to do的一个例子但是，当我在同一级别有很多元素时，最后一个分支下降，我希望我的div在溢出时扩展，我尝试过overflow-x：auto;溢出：汽车;但它不起作用。我从列表中检索了我的“叶子”，所以我不知道会有多少元素。

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

.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;
}

  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;
}

  display: inline-block;

  -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 {

}
/*Connector styles on hover*/

CSS也可以提供帮助：

  • display:table;它允许容器缩小/扩展以适应内容大小。如果指定了width，则除非table-layout设置为fixed

    • ，否则它仍可展开

  • white-space:nowrap;会将任意内联（或内嵌框）保留在一行中。

  • display:inline-block;代替float。与white-space一起使用时，它不会换行/分成新行。

  • font-size，是代码缩进处理white-space的方法之一，它显示了代码行为/设置为内联框的位置。

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

  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
  display:table;/* added idem as for parent*/
  font-size:0;/* added because of white-space, remove it to see what it does  */

答案 1 :(得分：0)

- 使用JQUERY -

这不是最漂亮的，但这似乎有效：

total = 0
$('li:not(:has(ul))').each(function() {total += $(this).outerWidth() + 10})
$('.tree').width(total)

它正在做的是找到没有孩子的每个“孩子”。所以每个链的最低级别。 $('li:not(:has(ul))')

然后总结每个outerWidth，加上一点点填充以说明利润。

最后，将容器.tree的宽度设置为我们刚刚计算的大小。
