regarding to changing the font size

[kimcando]

hi, thank you in advance. I really like this theme.
By the way, how can I change the font size of the page(posts, about and so on..)
I only found the way to change the icon font size (TT) please, consider I'm not familiar with CSS things..
which file should I change to make fonts bigger?

thanks
