You have to use text styles for the app to know which font size etc. you want to use in each variant. It takes a bit of learning and getting used to but then it's very easy to set up and maintain your site. Take a look for 'Text Styles' in the Help file. In that chapter there's also a link to 'Responsive Web Design' with more information about variants.
You might want to experiment with the Text Styles feature in a dummy website before working on the site you want to build.
