Add underline to text in this project page that I am using from an older template.

Can anyone look at this homepage that was started from an older template before squarespace changed from that format. I like the background change when you hover over the text, but I don't think many people will realize it will change when you do so I'd like to underline each word: Traditional, Transitional & Modern so people realize they link to that style portfolio. Anyone have any ideas of how to do that? I asked chat and they said it has to be done in custom code because they are project pages.

Thanks,
