# CSS Styling Approaches Reference
|
||||
|
||||
## Comparison Matrix
|
||||
|
||||
| Approach | Runtime | Bundle Size | Learning Curve | Dynamic Styles | SSR |
|
||||
|----------|---------|-------------|----------------|----------------|-----|
|
||||
| CSS Modules | None | Minimal | Low | Limited | Yes |
|
||||
| Tailwind | None | Small (purged) | Medium | Via classes | Yes |
|
||||
| styled-components | Yes | Medium | Medium | Full | Yes* |
|
||||
| Emotion | Yes | Medium | Medium | Full | Yes |
|
||||
| Vanilla Extract | None | Minimal | High | Limited | Yes |
|
||||
|
||||
## CSS Modules
|
||||
|
||||
Scoped CSS with zero runtime overhead.
|
||||
|
||||
### Setup
|
||||
|
||||
```tsx
|
||||
// Button.module.css
|
||||
.button {
|
||||
padding: 0.5rem 1rem;
|
||||
border-radius: 0.375rem;
|
||||
font-weight: 500;
|
||||
transition: background-color 0.2s;
|
||||
}
|
||||
|
||||
.primary {
|
||||
background-color: #2563eb;
|
||||
color: white;
|
||||
}
|
||||
|
||||
.primary:hover {
|
||||
background-color: #1d4ed8;
|
||||
}
|
||||
|
||||
.secondary {
|
||||
background-color: #f3f4f6;
|
||||
color: #1f2937;
|
||||
}
|
||||
|
||||
.secondary:hover {
|
||||
background-color: #e5e7eb;
|
||||
}
|
||||
|
||||
.small {
|
||||
padding: 0.25rem 0.5rem;
|
||||
font-size: 0.875rem;
|
||||
}
|
||||
|
||||
.large {
|
||||
padding: 0.75rem 1.5rem;
|
||||
font-size: 1.125rem;
|
||||
}
|
||||
```
|
||||
|
||||
```tsx
|
||||
// Button.tsx
|
||||
import styles from './Button.module.css';
|
||||
import { clsx } from 'clsx';
|
||||
|
||||
interface ButtonProps {
|
||||
variant?: 'primary' | 'secondary';
|
||||
size?: 'small' | 'medium' | 'large';
|
||||
children: React.ReactNode;
|
||||
onClick?: () => void;
|
||||
}
|
||||
|
||||
export function Button({
|
||||
variant = 'primary',
|
||||
size = 'medium',
|
||||
children,
|
||||
onClick,
|
||||
}: ButtonProps) {
|
||||
return (
|
||||
<button
|
||||
className={clsx(
|
||||
styles.button,
|
||||
styles[variant],
|
||||
size !== 'medium' && styles[size]
|
||||
)}
|
||||
onClick={onClick}
|
||||
>
|
||||
{children}
|
||||
</button>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Composition
|
||||
|
||||
```css
|
||||
/* base.module.css */
|
||||
.visuallyHidden {
|
||||
position: absolute;
|
||||
width: 1px;
|
||||
height: 1px;
|
||||
padding: 0;
|
||||
margin: -1px;
|
||||
overflow: hidden;
|
||||
clip: rect(0, 0, 0, 0);
|
||||
border: 0;
|
||||
}
|
||||
|
||||
/* Button.module.css */
|
||||
.srOnly {
|
||||
composes: visuallyHidden from './base.module.css';
|
||||
}
|
||||
```
|
||||
|
||||
## Tailwind CSS
|
||||
|
||||
Utility-first CSS with design system constraints.
|
||||
|
||||
### Class Variance Authority (CVA)
|
||||
|
||||
```tsx
|
||||
import { cva, type VariantProps } from 'class-variance-authority';
|
||||
import { cn } from '@/lib/utils';
|
||||
|
||||
const buttonVariants = cva(
|
||||
// Base styles
|
||||
'inline-flex items-center justify-center rounded-md text-sm font-medium ring-offset-background transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:pointer-events-none disabled:opacity-50',
|
||||
{
|
||||
variants: {
|
||||
variant: {
|
||||
default: 'bg-primary text-primary-foreground hover:bg-primary/90',
|
||||
destructive: 'bg-destructive text-destructive-foreground hover:bg-destructive/90',
|
||||
outline: 'border border-input bg-background hover:bg-accent hover:text-accent-foreground',
|
||||
secondary: 'bg-secondary text-secondary-foreground hover:bg-secondary/80',
|
||||
ghost: 'hover:bg-accent hover:text-accent-foreground',
|
||||
link: 'text-primary underline-offset-4 hover:underline',
|
||||
},
|
||||
size: {
|
||||
default: 'h-10 px-4 py-2',
|
||||
sm: 'h-9 rounded-md px-3',
|
||||
lg: 'h-11 rounded-md px-8',
|
||||
icon: 'h-10 w-10',
|
||||
},
|
||||
},
|
||||
defaultVariants: {
|
||||
variant: 'default',
|
||||
size: 'default',
|
||||
},
|
||||
}
|
||||
);
|
||||
|
||||
interface ButtonProps
|
||||
extends React.ButtonHTMLAttributes<HTMLButtonElement>,
|
||||
VariantProps<typeof buttonVariants> {
|
||||
asChild?: boolean;
|
||||
}
|
||||
|
||||
const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(
|
||||
({ className, variant, size, ...props }, ref) => {
|
||||
return (
|
||||
<button
|
||||
className={cn(buttonVariants({ variant, size, className }))}
|
||||
ref={ref}
|
||||
{...props}
|
||||
/>
|
||||
);
|
||||
}
|
||||
);
|
||||
```
|
||||
|
||||
### Tailwind Merge Utility
|
||||
|
||||
```tsx
|
||||
// lib/utils.ts
|
||||
import { type ClassValue, clsx } from 'clsx';
|
||||
import { twMerge } from 'tailwind-merge';
|
||||
|
||||
export function cn(...inputs: ClassValue[]) {
|
||||
return twMerge(clsx(inputs));
|
||||
}
|
||||
|
||||
// Usage - handles conflicting classes
|
||||
cn('px-4 py-2', 'px-6'); // => 'py-2 px-6'
|
||||
cn('text-red-500', condition && 'text-blue-500'); // => 'text-blue-500' if condition
|
||||
```
|
||||
|
||||
### Custom Plugin
|
||||
|
||||
```js
|
||||
// tailwind.config.js
|
||||
const plugin = require('tailwindcss/plugin');
|
||||
|
||||
module.exports = {
|
||||
plugins: [
|
||||
plugin(function({ addUtilities, addComponents, theme }) {
|
||||
// Add utilities
|
||||
addUtilities({
|
||||
'.text-balance': {
|
||||
'text-wrap': 'balance',
|
||||
},
|
||||
'.scrollbar-hide': {
|
||||
'-ms-overflow-style': 'none',
|
||||
'scrollbar-width': 'none',
|
||||
'&::-webkit-scrollbar': {
|
||||
display: 'none',
|
||||
},
|
||||
},
|
||||
});
|
||||
|
||||
// Add components
|
||||
addComponents({
|
||||
'.card': {
|
||||
backgroundColor: theme('colors.white'),
|
||||
borderRadius: theme('borderRadius.lg'),
|
||||
padding: theme('spacing.6'),
|
||||
boxShadow: theme('boxShadow.md'),
|
||||
},
|
||||
});
|
||||
}),
|
||||
],
|
||||
};
|
||||
```
|
||||
|
||||
## styled-components
|
||||
|
||||
CSS-in-JS with template literals.
|
||||
|
||||
```tsx
|
||||
import styled, { css, keyframes } from 'styled-components';
|
||||
|
||||
// Keyframes
|
||||
const fadeIn = keyframes`
|

|
||||
to { opacity: 1; transform: translateY(0); }
|
||||
`;
|

|

// Base button with variants
|

$variant?: 'primary' | 'secondary' | 'ghost';

## Emotion
|
||||
|

Flexible CSS-in-JS with object and template syntax.
|

|

|

## Vanilla Extract
|
||||
|
||||
Zero-runtime CSS-in-JS with full type safety.
|
||||
|
||||
```tsx
|

// Recipe (like CVA)

|

```
|

```tsx

import { button, type ButtonVariants, themeClass } from './styles.css';

}
|

|
||||
// App.tsx - wrap with theme
|

function App() {
|

return (
|

<div className={themeClass}>
|
||||
<Button variant="primary" size="large">
|
||||
Click me
|
||||
</Button>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
### Critical CSS Extraction
|
||||
|
||||
```tsx
|
||||
// Next.js with styled-components
|
||||
// pages/_document.tsx
|
||||
import Document, { DocumentContext } from 'next/document';
|
||||
import { ServerStyleSheet } from 'styled-components';
|
||||
|
||||
export default class MyDocument extends Document {
|
||||
static async getInitialProps(ctx: DocumentContext) {
|
||||
const sheet = new ServerStyleSheet();
|
||||
const originalRenderPage = ctx.renderPage;
|
||||
|
||||
try {
|
||||
ctx.renderPage = () =>
|
||||
originalRenderPage({
|
||||
