Quincy Template - Bottom Nav Links Overlap

Site URL: https://www.madebyrach.net/portfolio/lifestyle

I am trying to fix the font size on my bottom links of my portfolio.  They look fine on Desktop and on Mobile when the phone is turned landscape, but the words overlap when on Mobile and viewing it portrait (see photo for reference).

Is there a place I can inject code or customize CSS to alter the size of the font to make it smaller?

Thank you!
