HTML/CSS：包含 UL/LI 的 DIV 的动态宽度

Question

我使用http://thecodeplayer.com/walkthrough/css3-family-tree 处的代码创建了一个动态分层组织结构图。图表的宽度会根据仓位的数量而有所不同。

问题是图表的宽度是否大于浏览器窗口 org.通过保持与窗口相同的大小并扰乱结构而不是使用滚动条扩展窗口的流程，图表会变得混乱。 （小提琴：http://jsfiddle.net/euwx9qvq/）

* {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{

.tree li::after{

any siblings*/

                </li>
            </ul>
        </li>
    </ul>
</div>

我在 CSS 中为 DIV 添加了一个非常大的宽度，以便暂时绕过它。

但是宽度太大，空白的滚动会变得太长。

我正在尝试做的是让 DIV 动态地成为正确的大小，而无需在 CSS 中硬编码宽度，并使滚动条滚动到确切的大小，而不是更多。

谢谢。

我可以通过将它添加到树的 li 来修复它

display: inline-block;
white-space: nowrap;
vertical-align: top;
margin: 0 -2px 0 -2px;
text-align: center;
