Hi seanmcel
These elements are inheriting style from J2store, unfortunately, JA Sugite doesn't support override style for J2Store by default, you should contact its provider for help on these customization.
FYI: you can use the Inspect element in your browser >> right click on the button you want to customize style
then you can add your custom css into the file: /templates/ja_sugite/css/custom.css
