In FlatBox theme, I believe the main CSS controlling part is flatbox-core.min.css. All the code in that file is tangled. (I am not familiar with .min.css thingy though). From that tangled up codes, I am not sure which line or portion is responsible for the font size of question body and comment body.
Can any one please tell me which code shall I need to change for changing the font size of question body as well as comment body?
I am running Q2A 1.7 in a localhost.
