Modify home page background when using unitheme 2!

I want to modify the home page background only the home page without affecting other pages, I am using unitheme2
I tried the solutions provided in other discussions they id not work! any suggestions :roll_eyes:

You should add extra class to the body in the index.tpl file and add necessary background to the CSS section of the Theme editor

Thanks, under which folder the index.tpl is located! I cant find if I am using unitheme2

It is located in the parent theme

design/themes/responsive/templates/index.tpl

I added the class in the index.tpl and in the theme editor added the css class
body.homepage-background {
background-color: #1b1b1b !important;
background-size: cover;
background-repeat: no-repeat;
background-position: center center;
}

I also tried
.homepage-background {
background-color: #1b1b1b !important;
background-size: cover;
background-repeat: no-repeat;
background-position: center center;
}

Still did not work! am I missing anything!

I was able to do it though by adding a class to all the different elements in the layout page and then adding it to the theme editor:
.darkBackgroundHomePage .container-fluid-row .row-fluid {
background-color: #1b1b1b !important;
background-repeat: no-repeat;
background-size: cover;
}

.darkBackgroundHomePage {
background-color: #1b1b1b !important;
background-repeat: no-repeat;
background-size: cover;
}

Looks like there is no ability to set up background just for body. Use new class as parent to add custom styles for child elements
