I type “custom script” into help window and cannot find a link to custom script user guide.
Thank you for reaching out via our Community! We have do have a few tutorials that will help with certain aspects of using CSS, but we do not have a guide that will walk you through learning CSS. I have included some processes below that I think will help give you an idea of what we cover. I hope these are helpful. Thanks again for your time and have a great week!
