How to bold the individual item titles on a simple list in the 7.1?

I'm trying to bold the individual titles on a simple list and can't seem to find the setting or a code online to change this. My client wants it bolded. Any insight on a setting that can be changed or a code I can inject would be appreciated. Thanks!

This can be achieved with Custom CSS, can you share the website URL and location if this List? Thanks!

Here is the URL and the password since it's not yet public:
