Font Size Too Small

Hello,

I purchased and installed the theme Majestic - 1.8x Series Dark Edition - Best Dark Creative Premium MyBB Theme.

I love it, but there is one issue.

Is it possible to make the font size bigger?

It's too small for me.

I prefer to have font size = 14px

I do NOT know anything about CSS at all.

If you give me specific instructions on how to fix this, I will try my best.
