Layouts responsivos com CSS moderno

O que esta skill faz

Esta skill reúne padrões modernos para layouts que se adaptam a diferentes espaços e contextos. Ela aborda componentes responsivos, escalas fluidas, imagens, navegação, tabelas, touch targets e problemas comuns de viewport móvel.

Quando usar

• Criar um layout mobile-first com CSS Grid
• Adaptar componentes usando container queries
• Implementar tipografia e espaçamento fluidos
• Corrigir overflow horizontal em telas pequenas
• Projetar navegação e tabelas responsivas

Como usar

1. Revise o repositório, os tokens e os breakpoints existentes
2. Comece pelo conteúdo na menor largura relevante
3. Use unidades fluidas, Grid, Flexbox ou container queries conforme o contexto
4. Otimize imagens e mantenha alvos de toque adequados
5. Teste em larguras variadas e, quando possível, em dispositivos reais

O que revisar antes de instalar

• Simuladores não reproduzem todos os comportamentos de dispositivos reais
• Breakpoints devem surgir do conteúdo, não de uma lista genérica de aparelhos
• Container queries dependem da estrutura de containers definida pela interface
• A skill não garante desempenho sem medição

# Responsive Design

Master modern responsive design techniques to create interfaces that adapt seamlessly across all screen sizes and device contexts.

## When to Use This Skill

- Implementing mobile-first responsive layouts
- Using container queries for component-based responsiveness
- Creating fluid typography and spacing scales
- Building complex layouts with CSS Grid and Flexbox
- Designing breakpoint strategies for design systems
- Implementing responsive images and media
- Creating adaptive navigation patterns
- Building responsive tables and data displays

## Detailed patterns and worked examples

Detailed pattern documentation lives in `references/details.md`. Read that file when the navigation tier above is insufficient.

## Best Practices

1. **Mobile-First**: Start with mobile styles, enhance for larger screens
2. **Content Breakpoints**: Set breakpoints based on content, not devices
3. **Fluid Over Fixed**: Use fluid values for typography and spacing
4. **Container Queries**: Use for component-level responsiveness
5. **Test Real Devices**: Simulators don't catch all issues
6. **Performance**: Optimize images, lazy load off-screen content
7. **Touch Targets**: Maintain 44x44px minimum on mobile
8. **Logical Properties**: Use inline/block for internationalization

## Common Issues

- **Horizontal Overflow**: Content breaking out of viewport
- **Fixed Widths**: Using px instead of relative units
- **Viewport Height**: 100vh issues on mobile browsers
- **Font Size**: Text too small on mobile
- **Touch Targets**: Buttons too small to tap accurately
- **Aspect Ratio**: Images squishing or stretching
- **Z-Index Stacking**: Overlays breaking on different screens
