我对我正在制作的克隆网站有一些视差效果，我想做平滑的鼠标滚轮效果，当我添加jquery代码时，它覆盖了我应该用滚动移动的背景图像 jQuery代码：
此代码的哪一部分负责使我的背景变白？

你可以为你添加'！important'css background-image
infile="8Mvyi.jpg"
gray=0.466
declare `convert "$infile" -colorspace XYZ -crop 90x40+106+208 +repage -format "rratio=%[fx:$gray/mean.r]\ngratio=%[fx:$gray/mean.g]\nbratio=%[fx:$gray/mean.b]\n" info:`
