Set size & font for each family of fonts

Hi, I would like that you add in “my site” “customize” the possibly to edit the size of each family of script for example the Hebrew or Arabic, Cyrrilic or Greek, are smaller than Latin is with the same fonts, and I would like to be able to set the size and fonts for all of them in on time, without needing to do it each time one by one, with HTML code…

I have a page were I imagine new vorths & terms, by using the binary root that I deciphered, and for each of them I write them in all script (Latin Catholic, Greek & Slavic orthodox, Syriac Nazari, Arabs Islamic, Hebrew Judaism, and sometime in Sanskrit (but I don’t know well that script)…

So I really need this stuff for my page…

Thank…
