要实现天猫商城环境固定不动，控制模块透明的实际效果，其实就是并没有相匹配的编码的。完成下去只是一个简单创造性思维。并没有什么代码。不过我可能或是好多人不明白，简言之便是在DIV架构里边再插进一次固定不动环境。
下边实际的有2个天猫店铺透明背景的作用完成方式：
1.网页页面固定不动环境通用性技巧：立即在导航栏自定css中键入
主要参数：
background:url(背景图案详细地址)————键入详细地址
no-repeat————环境不重复
fixed————固定不动环境（相对于电脑浏览器）
center top————环境部位（center相对于电脑浏览器垂直居中，top相对于电脑浏览器顶端两端对齐）
层级关系如下所示：
可以看出；设置的body固定不动背景图案会在乳白色自定控制模块下边，控制模块不透明。就出天猫商城环境不全透明的难题。
2.怎样解决？
变化层级关系：
将确定的环境层放进控制模块默认设置白背景上，将其压着最下面，那样，完成透明背景。
层级关系编码：
