Compare utility-first Tailwind with scoped CSS Modules. When to use each and how to keep styles maintainable.
How you style React components affects consistency and maintenance. Here’s Tailwind vs CSS Modules in practice.
Tailwind and CSS in React
Tailwind CSS
Model — Utility classes in the template. className="flex gap-4 p-4 rounded-lg". Configure theme in tailwind.config.js.
Pros — Fast iteration, consistent design tokens, small production CSS with purging, no context switching to a stylesheet. Great with component libraries (e.g. Headless UI).
Cons — Long class strings; some prefer separation of structure and style. Requires learning the utility set.
CSS Modules
Model — Per-file stylesheets; class names are scoped. import styles from './Button.module.css' then className={styles.button}.
Pros — Real CSS (selectors, media queries), no new syntax, scoped by default. Familiar to CSS-native developers.
Cons — Another file per component; shared tokens need a strategy (variables, preprocessor).
Usage in React projects (survey):

When to use which
Tailwind — New projects, design systems with tokens, rapid UI work. CSS Modules — When you want full CSS power, existing CSS skills, or minimal tooling. You can mix (e.g. Tailwind for layout, modules for complex components).

Takeaway
Both are valid. Tailwind speeds up UI and enforces consistency; CSS Modules keep styling in real CSS files. Choose by team preference and project needs.
