Hi: Is there any way to globally increase all font sizes in wpForo as otherwise we have to identify every small text element and change the font size. I would like to enlarge all font by about 125% - 150% of current size.  f this can be done, can you please give me the css code? 

If it's not possible globally, could you give me a list of css items to set an increase of font size and also give me the css code for each item?

Thanks in advance for the help.
