🔄 Workflow

Kaynak: MDN - Container Queries & Utopia - Fluid Responsive Design

Aşama 1: Viewport & Layout Strategy

• Mobile First: Tasarımı en küçük ekran boyutundan başlayarak kurgula.
• Breakpoints Selection: Cihaz bazlı değil, içerik bazlı (Content-driven) kırılma noktaları belirle.
• Fluid Scaling: Typography ve spacing için clamp() fonksiyonlarını hesapla ve entegre et.

Aşama 2: Modern CSS Implementation

• Container Queries: Komponentlerin içindeki bulundukları alana göre (Viewport değil) şekil almasını sağla.
• Grid/Flex Optimization: Kompleks layout'lar için CSS Grid (Area naming) ve Flexbox (Gap) kullan.
• Image Optimization: srcset ve aspect-ratio kullanarak görsel yüklemelerini ve düzenini optimize et.

Aşama 3: Performance & Accessibility Audit

• Lighthouse Check: Core Web Vitals (LCP/CLS) metriklerini mobil için optimize et.
• Interaction Check: Dokunmatik (Touch) alanların yeterli boyutta (min 44x44px) olduğunu doğrula.
• User Preferences: prefers-color-scheme ve prefers-reduced-motion desteğini test et.
