I thought the image was going to show up irrespective of if I added a banner topic or not.
I just added the banner topic, but the background image I defined in the CSS is simply being ignored!
Here is the banner image code 
/> / banner
#banner {
border-radius: 0;
box-shadow: none;
background: url(“http://community.world-like-home.com/uploads/default/optimized/1X/b6c6b89e0a7ff4b8ffd6cfc97bd7d8fb8c39774c_1_690x251.jpg”) no-repeat;
padding: 20px;
max-height: inherit;
background-size: cover;
background-color: rgba(255, 255, 255, .6);
background-blend-mode: color;
}
Am guessing there’s something am not doing right ?
