## Best Practices
### DO:
- Use design tokens for all values
- Use utility classes for common patterns
- Keep component styles in CSS, not inline JS
- Use semantic HTML elements
- Maintain consistent spacing using the spacing scale
### DON'T:
- Use hardcoded pixel values
- Use inline styles in JavaScript
- Mix different border-radius values arbitrarily
- Skip the spacing scale with custom values
- Use arbitrary font sizes outside the type scale
## Migration Guide
### From hardcoded values:
```css
/* Before */
.element {
padding: 16px;
font-size: 14px;
border-radius: 4px;
margin-bottom: 24px;
}
/* After */
.element {
padding: var(--space-4);
font-size: var(--text-sm);
border-radius: var(--radius-sm);
margin-bottom: var(--space-6);
}
```
### From inline styles:
```javascript
// Before
element.style.cssText = 'display: flex; gap: 8px; padding: 16px;';
// After
element.classList.add('flex', 'gap-2', 'p-4');
```
## Themes
The design system supports multiple themes. Each theme defines color variables while maintaining consistent spacing, typography, and other design tokens.
Available themes:
- `monochrome` (default)
- `dark`
- `ocean`
- `purple`
- `forest`
- `mocha`
- `machiatto`
- `frappe`
- `latte`
- `white`
## Notes
- The `--highlight-rgb` variable must be in comma-separated RGB format (e.g., `245, 245, 245`) for use with `rgb()` function
- All spacing values are in rem units for accessibility
- The design system is mobile-first and responsive
