Hi JayL,
This would require custom CSS as this is not a renew’s stack feature by default and is outside of our support scope, but we will do our best to help you getting started with the customization but we will not be able to implement it. You can try adding the following code in the Theme Options > CSS:
.x-site > .x-container {
position: relative;
}
.x-site > .x-container:before {
content: "";
display: block;
position: absolute;
top: -35px;
bottom: -10000em;
bottom: 0;
width: 10000em;
background-color: #fff;
}
.x-content-sidebar-active .x-site > .x-container:before {
right: 28%;
}
Please note that the code provided above serves as a guide only and is to help you in getting started so implementing it and maintaining the code will be out of our support scope and for further maintenance for new possible versions of the theme that may cause the customization to break, you will need to hire a developer.
Don’t forget to clear all caches including your browser’s cache after adding the code.Hope this helps!
