【问题描述】：
我正在尝试制作 HTML/CSS 流程图。我希望所有东西都适合宽度方向的一个屏幕视图，但目前还不是。我不介意单个盒子的宽度较小，盒子内的文字会换行。
我希望有人能够查看 CSS 代码 - 似乎应该有一个快速修复！
我从那里得到了原始代码： http://thecodeplayer.com/walkthrough/css3-family-tree

<style>
li {
white-space: nowrap; // stop the wrapping in the first place
}
/*Now the CSS*/
* {margin: 0; padding: 0;}
.greenBox {
border: 2px solid #007f00 !important;
background-color:#e5ffe5;

.redBox {

/*We will use ::before and ::after to draw the connectors*/
.tree li::before, .tree li::after{

any siblings*/

/*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{

/*Adding back the vertical connector to the last nodes*/

}
/*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;
}
/*Thats all. I hope you enjoyed it.
Thanks :)*/
