That’s correct, you do not need to understand code at all if you do not wish to.
As shown in another topic of yours here:

We’ve written the code for you, you need only copy and paste that code under Appearance > StartupPro Options > Custom CSS and Save, nothing more.
If you have a follow up question there or on other requests, please let us know.
Otherwise, please confirm that you still wish for a refund.
