How can I change both the font and font size for the body text as well as the page header titles and menu in Interface (Free)?
I tried changing the stylesheet directly (I know it’s not recommended, but I was at a loss after trying the custom CSS) where it said PT Sans, then tried entering custom CSS via the Design Options, but neither caused any changes?
We recommended not to change the code because if you change the code then while updating to our new version all your customisation code will be lost. So better make child theme and first unhook the functions and the edit the code.
