Hueman Theme 3 column, one background image

I’m trying to get one continuous background image with a three column layout. I’ve made the header transparent, removed the gray images from the two sidebars and used my image in the wrapper. However, both sidebars and the main content have a white background… I’ve tried all I know how to try! Please help!!! Here’s my styles in Advanced CSS Editor (plugin)

Here’s my development site: https://cleurbanwinery.ccadinc.com/ and here’s the look I’m after (site built in website builder, client wants wordpress): https://www.cleurbanwinery.com/

#header {background: transparent;}
.col-3cm .main-inner {background-image: none;}
.col-3cm .main {background-image: none;}
#wrapper {
background-image: url(“https://cleurbanwinery.ccadinc.com/wp-content/uploads/2016/04/cle-urban-winery-white-brick-background.png”); }

Thanks so much!!!
