Design tokens are the visual design atoms of the design system — specifically, they are named entities that store visual design attributes. We use them in place of hard-coded values (such as hex values for color or pixel values for spacing) in order to maintain a scalable and consistent visual system for UI development1. Design tokens are available for different platforms and frameworks, such as Lightning Web Components, Aura Components, CSS, iOS, and Android2. Design tokens can be customized to apply branding and theming to components and applications3. Utility classes are CSS classes that provide common styling properties, such as margins, padding, borders, and text alignment1. Design patterns are reusable solutions to common design problems, such as navigation, forms, and data visualization. References: Design Tokens - Lightning Design System, SLDS Design Tokens | Lightning Web Components Developer Guide | Salesforce Developers, Styling with Design Tokens - Salesforce Developers, [Design Patterns - Lightning Design System]
