UL gaps between LI items

First, I’m not quite sure if I am posting in the right subforum. If not, please accept my apologies and move as desired.

I am interested in reducing the spacing between list items (LI) in my unordered lists (UL) in posts on my micro.blog site. I’ve had a look at the main CSS of the theme I am using and I’m not seeing anything that has increased the gaps between list items, but I’m not a wizard with CSS. I am also not a wizard with micro.blog or hugo, which doesn’t help.

Normally, I would reach out to the author of the theme and ask if there was a way to easily adjust that, but having a look at their main site makes it seem like they are focusing on other non- micro.blog projects at this point.

Given my ignorance of how the parts at micro.blog interact, would this likely be a CSS issue that might be remidied by a code snippet in the custom CSS or am I really off base with that idea?

I did get in touch with the theme author, and it turns out this block put into the Custom CSS was rhe answer:

.page-content li {
margin-top: 0px;
margin-bottom: 0px;
}

I’m grateful that he responded quickly even know he is doing other things atm.
