Comparison
Tailwind vs CSS Modules: styling your app
Two popular approaches to styling React applications, each with distinct advantages. Here's how they compare.
Tailwind CSS
Utility-first CSS framework. Style directly in your markup with atomic classes. Rapid development with consistent design.
CSS Modules
Scoped CSS files per component. Traditional CSS with automatic class name scoping to prevent conflicts.
| Feature | Tailwind CSS | CSS Modules |
|---|---|---|
| Development Speed | Very fast — style inline | Moderate — separate file switching |
| Bundle Size | Small — purges unused utilities | Varies — depends on CSS written |
| Learning Curve | Moderate — learn utility names | Low — just CSS with scoping |
| Consistency | High — constrained design tokens | Requires discipline |
| Responsive Design | Excellent — built-in breakpoint prefixes | Manual media queries |
| Dark Mode | Built-in dark: prefix | Manual implementation |
| Readability | Polarizing — long class strings | Clean — semantic class names |
| Customization | Extensive config, custom plugins | Full CSS freedom |
When to choose each
Choose Tailwind CSS
Choose Tailwind when you want rapid prototyping, consistent design tokens, built-in responsive and dark mode, and your team is comfortable with utility classes.
Choose CSS Modules
Choose CSS Modules when your team prefers traditional CSS, you need complex animations, or you're working on a project with an existing CSS architecture.
Our verdict
We use Tailwind CSS for all projects. The development speed, built-in design system constraints, and responsive/dark mode utilities make it the most productive choice. The initial 'ugly markup' concern disappears once you experience the speed boost.
