Hi, Kristina.
Geoff definitely went way above our Scope of Support / Terms, where it states that we do not provide CSS/styling or theme-integration assistance, which is where this request falls into.
Might it be that the CSS you implemented (of your own and/or from Geoff) was wiped away by an update?
If not and you share a link where we can see the issue, we might be able to offer just a bit more assistance here. However, I’ll again refer to our support limitations (linked above) and make sure you understand that we will not be able to provide ongoing fixes for this if it doesn’t play nice with your site’s theme or other plugin styles in the future.
Thank you very much for your understanding.
If you need some coding help, you may want to ask your developer, theme author, or reference our documentation and list of known customizers.
