Utility-first CSS and the Tailwind mental model

Think in CSS decisions

When designing a component, break the visual result into decisions: display, positioning, sizing, spacing, typography, colors, borders, effects and responsive behavior. Tailwind gives you utilities for these decisions.

Composition instead of semantic styling classes

Traditional CSS might define .primary-button and put many declarations inside it. Tailwind lets the component itself express those declarations. This can reduce the need to jump between a template and a large CSS file.

Abstraction still matters

Utility-first does not mean duplicating hundreds of classes everywhere. When a UI pattern is repeated, create a component in your framework or extract a carefully chosen custom utility/component rule.
