Hello @waynepatt58,
The example url here: https://www.nobledesktop.com/web-development-courses-nyc does not have the same structure as what you have in your sidebar.
To get you started, you start using this css code:
.x-sidebar {
padding: 10px;
background-color: #272E3D;
box-shadow: 0 18px 20px 0 rgba(7,15,33,0.3);
border-radius: 8px;
overflow: hidden;
}
Please note that custom coding is outside the scope of our support. Issues that might arise from any modifications, the use of custom code and further enhancements should be directed to a third party developer.
To have a rounded corners for the elements, you can check out this css tutorial:
Thank you for your understanding.
