Use CSS solutions instead of JavaScript state management for simple styling and interactions. This approach improves maintainability, reduces complexity, and follows web standards best practices.
Examples of when to apply this:
- Use CSS `:hover` pseudo-classes instead of `onMouseEnter`/`onMouseLeave` event handlers
- Implement show/hide behavior with CSS `display` or `visibility` properties rather than React state
- Apply styling through CSS classes instead of inline styles
Example transformation:
```tsx
// Instead of JavaScript state management:
const [isOpen, setIsOpen] = useState(false);
return (
);
/* CSS */
.dropdown:not(:hover) .dropdown-menu {
display: none;
}
```
This approach reduces JavaScript complexity, improves performance, and makes the code more maintainable by leveraging native browser capabilities.
