Need to increase font size on lists

My bulleted lists have smaller font than my paragraph size. I’ve read several posts here, but can’t locate anything in my Stylesheet with the code they suggest changing. I think it might be in the code below, because it has “list-style”
Can anyone tell me the specific line of code where I can increase the font size?
Thanks.

margin-bottom: 18px;
