我正在尝试创建一个家族树，而功能的最后一部分给我带来了一些困难。

“我的树”是一系列列表元素，所有元素都向左浮动。

我想要的是，如果树扩展超过屏幕大小，父div #c1应该允许用户水平滚动到树上。

现在发生的情况是，如果树的宽度大于#c1，那么树将自己包装，使其不可读。

我临时修正了这个问题，在#c1中添加了一个名为#c2的div，宽度为1000000 of。基本上，这棵树永远不会变大，所以它永远不会自己卷进来，用户可以在树上滚动。

我想要的是，在加载javascript时，以某种方式将#c2的宽度与树相匹配，或者以某种方式找到一个css解决方案。

我试过使用空白:现在，和许多其他解决方案，我已经找到了类似的问题，但似乎没有什么对我有用。

这里有一个纯CSS解决方案，如果您没有附加到浮动(这可能会给您带来其他困难-因为只有浮动子元素的父元素将有一个折叠的内容框，您的#c2div的高度为0，其内容是“挂起底部”)。

CSS中的3个步骤：

  1. 删除 #c2 {宽度: 100000px；} (您可以将#c2div完全从HTML中删除)
  2. 添加 .tree {空白: nowrap；}
  3. 更改.tree li选择器中的规则，使代码块看起来如下所示： .tree li {显示:内联块；垂直对齐:顶部；文本对齐:中心；列表样式类型:无；位置:相对；填充:20 px5px0 5px；-webkit-转换:所有0.5s；-moz-转换:全部0.5s；转换:所有0.5s；

这将使用display: inline-block将树的碎片水平地放置在一起，使用vertical-align: top将它们垂直对齐到容器的顶部，并在容器上放置white-space: nowrap，以确保它们不会流到新的线路上。请注意，保持div #c1上的overflow: auto很重要，或者将overflow-x: scroll放在div #树上，以启用您想要的水平滚动行为。

下面是工作片段：
