Padding between right sidebar widgets

Hello,

I would like to reduce the amount of padding between the widgets in the right sidebar. I have seen a few forum posts with CSS that you have suggested but none of them have worked for me. I use the Dev tools in Chrome to see the CSS and I have tried to target the widgets a few different ways but nothing works. The only way I could get anything to move was to use negative value margin which didn’t seem like a good idea here.

Will you please take a look at the page here?

Thank you very much!
