Question

我使用http://thecodeplayer.com/walkthrough/css3-family-tree处的代码创建了动态分层组织结构图。图表的宽度将根据位置数量而变化。

问题是图表的宽度是否大于浏览器窗口，组织。通过保持与窗口相同的大小并加扰结构而不是使用滚动条扩展窗口的流程，图表变得混乱。（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;

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

我在CSS中为DIV添加了一个非常大的宽度，暂时传递它。

但宽度太大，白色空间的滚动可能会太长。

我要做的是让DIV动态合适，不需要在CSS中硬编码宽度，滚动条滚动到确切的大小而不是更多。

谢谢。

我能够通过将其添加到树的li来修复它

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

HTML / CSS：包含UL / LI的DIV的动态宽度
