Modern CSS Techniques for Better Web Design

# Modern CSS Techniques for Better Web Design

CSS has evolved significantly. Let's explore modern techniques that make web design more powerful and flexible.

## CSS Grid vs Flexbox

### When to Use Grid
- Two-dimensional layouts
- Complex positioning
- Card-based designs

### When to Use Flexbox
- One-dimensional layouts
- Component alignment
- Navigation bars

## CSS Custom Properties

CSS variables provide dynamic theming capabilities.

```css
:root {
--primary-color: #3b82f6;
--secondary-color: #10b981;
}
```

## Container Queries

The future of responsive design:

```css
@container (min-width: 400px) {
.card {
display: flex;
}
}
```

## Advanced Selectors

Modern CSS selectors provide more precision:
- :has()
- :is()
- :where()

## Conclusion

Modern CSS offers powerful tools for creating responsive, maintainable designs.
