Hello,
Thanks for reaching out! To reduce/increase the margin/padding on the right side of the widget area, you’ll need to add some CSS. This article has some more details and examples on customizing widget styles with CSS, so I would recommend using that as a starting point.
We are a bit limited in the amount of support that we can provide for customizations, but if you get stuck or have any questions, please let me know! I’ll be happy to point you in the right direction 🙂
Thanks,
Jennifer
