display: grid;
grid-template-columns: 1fr 2fr;
}
}
CSS Grid & Flexbox Evolution

- Self-documenting code
8. Performance Optimization Focus
Core Web Vitals Priority
Google's Core Web Vitals remain critical:
- LCP (Largest Contentful Paint): < 2.5s
- FID (First Input Delay): < 100ms
- CLS (Cumulative Layout Shift): < 0.1
Optimization Techniques
- Image optimization (WebP, AVIF)
- Code splitting and lazy loading
- Resource hints (preload, prefetch)
- HTTP/3 adoption
- Critical CSS extraction
9. Accessibility First Development
WCAG 2.2 Compliance
Accessibility is no longer optional:
- Semantic HTML5
- ARIA attributes
- Keyboard navigation
- Screen reader optimization
- Color contrast compliance
Tools:
- axe DevTools
- Lighthouse accessibility audit
- WAVE browser extension
- Pa11y automated testing
10. Micro-Frontends Architecture
Scalable Frontend Architecture
Micro-frontends enable team autonomy:
- Module Federation: Webpack 5
- Single-SPA: Framework-agnostic
- qiankun: Alibaba's solution
