vB4 How to Change Font Size for the Entire Forum Board
 

I've tried searching for the answer but all relate to very complicated ways of finding stylevars, css classes, attributes and what not; all of which are very confusing to a beginner like me.

Is there a simple way to increase the font sizes for the entire board? The default installation which I've just done has fonts a little too small for me (and I"m sure many of my readers who don't have good eyesight).

Any help on this would be appreciated!
