什么是设计系统？

Ever notice how Google or Apple feel so consistent everywhere? That cohesion usually comes from a Design System — and that is exactly what you will learn here.

A Design System is the complete set of standards, docs, and reusable components for building a product — a single source of truth for design and code.

Building UI without a system is like building a house with no blueprint. A Design System brings consistency, speeds development, and lifts quality.

Visual style defines the look: color palettes, typography, and spacing rules. It is the aesthetic foundation every screen follows.

UI components are the pre-built, pre-coded blocks of your interface — buttons, inputs, nav bars — each with a defined look and behavior.

Documentation is the user manual: it spells out how to use each component and apply the style correctly, including accessibility and code.

A style guide is mostly static visual rules. A design system contains that guide but adds coded components, usage docs, and governance — a living product.

A component library is coded UI elements — one part of a design system. The system also adds principles, visual style, docs, and process.

Picture a LEGO kit: docs are the instructions, visual style is the colors, components are the bricks. The design system is the whole package.

Which of the following elements are typically included as part of a comprehensive design system?

A Design System is a holistic set of standards, components, and docs — far more than a style guide or component library alone. Great start!
