Hi there,
Not an overly easy one to figure out.
They’re using an empty element to apply the background image to the right sidebar of the page only, but I’m not sure if that would work with the current HTML.
You could try stretching the color all the way to the right like this:
.inside-right-sidebar:after {
content: "";
position: absolute;
background: #000;
width: 1000px;
display: block;
top: 0;
left: 100%;
bottom: 0;
background: #B6C9D0;
}
.inside-right-sidebar {
position: relative;
background: #B6C9D0;
}
body, html {
overflow-x: hidden;
}
