Understand Classic, child themes and the options for creating a storefront that fits your brand.
Classic storefront
Classic is the bundled storefront. Start with its responsive templates and review your store on desktop and mobile.
Child themes
A child theme can extend Classic using a theme.json manifest with parent set to classic, theme settings and CSS overrides.
Install a theme ZIP
Use Design → Themes to install and select a theme. A full spa-dist replacement can provide its own built storefront. Back up customizations and test a theme before publishing it.
