Ozcart includes a built-in live theme editor for you to use to change the style elements of the site yourself. For example, you can change the fonts to Google Fonts, change the colours, paddings, font sizes.
If you have a question about how to do something, you can ask it via our support system and we’d be happy to help you – within the limits of the cart’s functionality. We don’t provide specific help on achieving the look you want, but may be able to make suggestions on a best-efforts basis.
