适用于分步骤操作的页面导航图
实现结果如下
上图对应下述代码，稍作修改可以生成下图。
css代码如下：

scss
第一部分的css，可以通过scss 设置变量生成css ，方便计算每个步骤环节的高度宽度，使得流程线和流程的位置能对应显示，并且此案例的多行线是通过table的border的宽度实现，相关宽高的设置通过scss变量计算，能适应不同的情况的css编写，具体如下
//sass style
//-----------------------------------
@charset "utf-8";
/**单列宽度 单行高度 列数 行数*/
$dwidth: 300px;
$dheight: 30px;
//横向大环节个数
$anum: 4;
//纵向行个数
$bnum: 4;
$border: 10px;
$height:($dheight+$border) * $bnum - $dheight;
$allheight:($dheight+$border) * $bnum;
//圆圈直径
$circleA: 24px;
//文字
$textA: 16px;
body{font-size:12px;color:#000000; font-family:"Microsoft Yahei"; overflow-x:hidden; background:#ffffff;}
/**单列宽度 单行高度 列数 行数*/
.web-width{width: 1200px;margin:20px auto;}
.for-liucheng{width: $dwidth *$anum ;margin:0 0 0 0;height: $allheight;padding:0 0 0 0; position:relative;}
.liulist{float:left;width:$dwidth; height:$border;background:#CCCCCC;margin-top: ($height - $border)/2;}
.liulists{float:left;width:$dwidth; height:100%;}
.liutextbox{ position:absolute;width:100%;height:($dheight+$border) * $bnum;}
.liutext{float:left;width:$dwidth;text-align:center;margin-top: ($height - $border)/2-$circleA/2+$border/2;}
.liutexts{float:left;width:$dwidth;height:100%; text-align:center;margin-top: -$circleA/2+$border/2;}
.liutext_2{display:inline-block;float:left;width:100%; height:$allheight/$bnum+2px;text-align:center;padding-bottom: 0px;}
