The Theme Styles menu appears to the left of the preview area when you launch Page Builder. This is where you can customize attributes (like colour, font, and text size) of several of your theme’s design elements (like the header, logo, navigation, and footer). You can also turn other design elements off/on.

The theme’s elements are grouped based on where they appear on the storefront (like the homepage or checkout page) or what type of element it is (like a button or icon). The actual sections and their names may differ from theme to theme.
