Hi! Thanks for the quick response!
When viewed on my mobile (Android, Chrome browser), the font seems a little too big for me and are overlapping with each other, that's why I was trying to figure out how to change the size settings of the font.
Changing the Heading and Paragaph settings in the design area under 7.1 affects the entire site, but does not seem to affect the mobile navigation menu. The older CSS that worked in 7.0 does not seem to work in 7.1 either.
And thank you so much for the multilanguage site guide! It's on my roadmap and I'm really grateful to have a good starting point with your guides!!
