Change customizr background

@nikeo provided a number of classes:
.home = Front Page
.blog = Posts Page
.page = Other Pages
.page-id-n = Selected Page

So using this snippet, I’d use:

body.home {
background:     none;
}
body.page  {
/* Adjust the Image location 'wp-content/uploads/NAMEOFFILE.png' */
background:     url(/wp-content/uploads/NAMEOFFILE.png) repeat fixed 0 0  ;
}
/* Set the color (#FAFAFA) of the internal body */
#main-wrapper {
background-color: #FAFAFA;
margin-top:     0px ;
margin-bottom:  0px;
}

how to insert featured image as title background ? like twentyfourteen ?

Error in my previous post. .blog should be .post

Once again Mr rdellconsulting, you are a star! Thank you! I was close, I had ‘#body-home’ wrong class ??

thanks rdellconsulting
