Overview

User Interface (UI) is the visual part of your store — the buttons, menus, layouts, colors, and typography that shoppers see and interact with. On Shopify, UI is primarily determined by your theme, with customization through the Theme Customizer or code.

UI is what shoppers see. A clean, attractive UI builds trust and guides shoppers; a cluttered, confusing UI frustrates and loses them. UI is the visual layer of UX — together, they determine how shoppers experience your store.

UI pairs with user experience (UX) (the broader experience), themes (what defines it), and theme customizer (how you edit it). It's the visual design layer.
