Font Size in Berlin Theme

Hi,

I reviewed prior questions regarding font size but didn’t see exactly what I was looking for.

I’m using the Berlin Theme (not the latest updated version). I’m wondering if there is a way to change the font size in the Homepage Text area (that’s what it’s called on the admin side) and descriptions of Featured Items , Featured Collection, and Item descriptions.

I tried changing the heading sizes but that didn’t seem to affect anything, I also checked the HTML box on the Items admin side to change heading sizes but didn’t see any changes.

Can this only be accomplished by going into the CSS?
